Carmex Precision Tools Ltd. has announced two notable additions to its line of solid carbide end mills. The CR – Supercut Roughers are specifically designed for high-volume applications that require high metal removal rates in slotting, shouldering, and helical plunging.
The innovative roughing geometry results in smaller chips and low cutting forces, and a reinforced corner chamfer promotes additional strength for longer tool life. Designed for semi-finish profile and center cutting, the multi-flute design is constructed of ultra-fine carbide grade CR3 for high cutting edge stability and wear resistance. The tools also feature a new generation of PVD coating for High Performance Cutting (HPC) applications.
High Performance Cutting (HPC) is also characteristic of the new solid carbide roughers designed for aluminum machining. The optimal flute geometry delivers maximum metal removal rates and better chip evacuation, as well as low cutting forces. The reinforced corner chamfer promotes additional strength for longer tool life. Constructed of ultra-fine carbide grade CA5 for hardness and toughness, the tools are uncoated with a smooth polished surface finish that results in high cutting edge stability and wear resistance.
Jim White, National Sales Manager for Carmex USA, comments, “The new Supercut solid carbide end mills are the latest addition to the Carmex family of milling tools. Incorporating specially formulated carbide grades and, where applicable, the latest in PVD coating technology, they answer customer demands for high metal removal in both hard and abrasive materials and aluminum.”

- abrasive
abrasive
Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
- hardness
hardness
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.
- milling
milling
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.
- physical vapor deposition ( PVD)
physical vapor deposition ( PVD)
Tool-coating process performed at low temperature (500° C), compared to chemical vapor deposition (1,000° C). Employs electric field to generate necessary heat for depositing coating on a tool’s surface. See CVD, chemical vapor deposition.
- slotting
slotting
Machining, normally milling, that creates slots, grooves and similar recesses in workpieces, including T-slots and dovetails.
- wear resistance
wear resistance
Ability of the tool to withstand stresses that cause it to wear during cutting; an attribute linked to alloy composition, base material, thermal conditions, type of tooling and operation and other variables.
