Related Glossary Terms
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.
- chip clearance
In milling, the groove or space provided in the cutter body that allows chips to be formed by the inserts.
Space provided behind a tool’s land or relief to prevent rubbing and subsequent premature deterioration of the tool. See land; relief.
- computer-aided manufacturing ( CAM)
computer-aided manufacturing ( CAM)
Use of computers to control machining and manufacturing processes.
- edge preparation
Conditioning of the cutting edge, such as a honing or chamfering, to make it stronger and less susceptible to chipping. A chamfer is a bevel on the tool’s cutting edge; the angle is measured from the cutting face downward and generally varies from 25° to 45°. Honing is the process of rounding or blunting the cutting edge with abrasives, either manually or mechanically.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
Process of increasing the surface hardness of a part. It is accomplished by heating a piece of steel to a temperature within or above its critical range and then cooling (or quenching) it rapidly. In any heat-treatment operation, the rate of heating is important. Heat flows from the exterior to the interior of steel at a definite rate. If the steel is heated too quickly, the outside becomes hotter than the inside and the desired uniform structure cannot be obtained. If a piece is irregular in shape, a slow heating rate is essential to prevent warping and cracking. The heavier the section, the longer the heating time must be to achieve uniform results. Even after the correct temperature has been reached, the piece should be held at the temperature for a sufficient period of time to permit its thickest section to attain a uniform temperature. See workhardening.
Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.
Any manufacturing process in which metal is processed or machined such that the workpiece is given a new shape. Broadly defined, the term includes processes such as design and layout, heat-treating, material handling and inspection.
Structure of a metal as revealed by microscopic examination of the etched surface of a polished specimen.
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
- milling machine ( mill)
milling machine ( mill)
Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
Abrasive process that improves surface finish and blends contours. Abrasive particles attached to a flexible backing abrade the workpiece.
Angle of inclination between the face of the cutting tool and the workpiece. If the face of the tool lies in a plane through the axis of the workpiece, the tool is said to have a neutral, or zero, rake. If the inclination of the tool face makes the cutting edge more acute than when the rake angle is zero, the rake is positive. If the inclination of the tool face makes the cutting edge less acute or more blunt than when the rake angle is zero, the rake is negative.
- sawing machine ( saw)
sawing machine ( saw)
Machine designed to use a serrated-tooth blade to cut metal or other material. Comes in a wide variety of styles but takes one of four basic forms: hacksaw (a simple, rugged machine that uses a reciprocating motion to part metal or other material); cold or circular saw (powers a circular blade that cuts structural materials); bandsaw (runs an endless band; the two basic types are cutoff and contour band machines, which cut intricate contours and shapes); and abrasive cutoff saw (similar in appearance to the cold saw, but uses an abrasive disc that rotates at high speeds rather than a blade with serrated teeth).
On a rotating tool, the portion of the tool body that joins the lands. Web is thicker at the shank end, relative to the point end, providing maximum torsional strength.

The latest catalog contains around 300 pages and is packed with pioneering and high-performance tools designed to enhance productivity and quality in, for example, HSC, HPC, TSC and CSC machining, even for materials that are difficult to cut.”
In its new catalog, Inovatools presents a range of market-oriented tool solutions for a diverse range of applications such as tool and mold construction (MOLD & DIE), the automotive industry, aviation and aerospace industry (INOSPACE) and medical sector (INOMED). Whether mills, drills, reamers and counterbores, the modular cutting system INOSCREW or saw blades of all different kinds – from mini, diamond-coated and XL through to special versions, users can always find exactly the tools they need for their specific cutting operations. Inovatools has significantly expanded its product range in a number of different areas, with numerous new tools designed to ensure maximum quality and cost-effective performance for manufacturers – even in the case of high-tech materials that are difficult to cut.
One example is the curve segment mill CurveMax, which is deployed primarily in tool and mold construction. Dennis Marz: “The Curve Segment Cutting strategy – or CSC for short – is a prime example of how the company combines state-of-the-art, high-performance CAM software with powerful processing centers and innovative tool development to create pioneering new cutting techniques.”
Thanks to their special geometry, the new CurveMax mills from Inovatools permit bigger path distances and line jumps during pre-finishing and finishing. Although the working radius is larger than that of a traditional full-radius mill, the tool still has the same diameter. The new process increases surface quality and significantly shortens processing times.
Dennis Marz: “The CSC mills not only shorten processing times for finishing complex freeform surfaces but, in doing so, also deliver better surface quality than traditional standard, full-radius mills.”
Use the catalog to find the tools you need quickly and easily
The table of contents preceding each tool group in the catalog helps you to find your way around quickly and easily. Photos of each individual tool and numerous pictograms make it much easier for users to find the tools they need. Dennis Marz: “All the product areas in the catalog are clearly structured. Handy tabs at the sides of the pages make it quick and easy to find the right product class. Usage recommendations make it easier for users to quickly identify which tool is suitable for which material and application.”
The geometry of the special DeepMax deep-hole drills from the broad Inovatools VHM drill range, for example, is specially designed to ensure optimal chip removal for this application. To achieve this, Inovatools employs a special polishing technique that creates extremely smooth chip grooves. Four lands ensure outstanding hole quality even with oblique outlets and cross-drilled holes. The extremely smooth VAROCON high-performance coating, which was specially developed for the application, supports fast chip flow and ensures a long tool service life. Dennis Marz: “We are also using a newly developed process for edge preparation so that the cutting edges can be precisely optimized in line with the machining challenges of the deep-drilling process. This keeps cutting forces low, ensures smooth running and maximizes service life. With all these features, DeepMax deep-hole drills deliver outstanding performance in terms of service life and cutting values.”
“First Choice” products
To make it even easier for users to find a tool that is optimized for their applications, Inovatools has already narrowed down your choice and flagged these special recommendations in the catalog as “First Choice” products. Among other things, this is a quick and easy way to help users to find the advanced geometries and technologies that are most suitable for them. “First Choice” tools help users to instantly identify tools that will help them to reduce production times and deliver top surface quality while benefiting from a longer service life. This helps to cut tool and machinery costs – for example, with the top products for machining stainless steel. Dennis Marz: “Depending on the microstructure and alloy content, mills and drills struggle with phenomena like built-up edges, abrasiveness, work hardening, edge zone hardening and high temperatures in the intervention zone. Inovatools products are specially adapted in line with the requirements associated with carbide metal, cutting geometry, chip clearance and coatings. Thanks to their specific cutting and cooling strategy, they achieve optimal results in, for example, roughing and finishing processes. The top products from Inovatools bring the desired added value in terms of endurance and speed to HPC roughing and finishing processes – just look at the FightMax INOX mills featuring the DUOCON high-performance coating.”
For machining non-ferrous metals such as aluminum, Inovatools offers a range of options including the new ta-C tool range. The ta-C high-performance thin-layered coating on these tools ensures that acute rake angles and, in turn, cutting edges are retained. The smooth carbon surface and high coating hardness ensure that chips do not adhere to the tool cutting edges. This minimizes cold welding, which is why the ta-C coating is especially well suited to aluminum
In addition to the numerous new additions and special “First Choice” recommendations, the catalog features a range of practical information for cutters about Inovatools’ INOSHOP (online shop), INOQR (QR code reader), INOCUT (cutting data computer) and INOCAM (CAM/XML interface) as well as a range of web, Android and iOS apps, providing users with instant and comprehensive information and allowing them to access the required tool and its data directly and with just a few clicks.
