Series 33 Endmills

May 13,2013

SGS Tool Co. has added a new series of high-performance 3-flute endmills for difficult-to-machine materials and challenging applications. The new product series has launched in support of the company's ongoing commitment to high-performance tooling and continuous improvement.

Available with a corner radius, the new Series 33 endmills are reportedly ideal for aggressive ramping, pocketing and slotting of materials such as stainless steel, titanium and Inconel. The open structure at the axial end accommodates material flow and load reduction during machining operations involving aerospace structure components, medical replacement parts and automotive performance components.

Stepped Core Design: Provides optimal chip control and rigidity when the flute is completely engaged.

Unique Variable Geometry: Engineered variable helix and pitch configuration offer chatter and vibration suppression.

Symmetrical End Gashing: Superior balance combined with a high level of strength and ramping capabilities.

The new tool series was developed using the latest in engineering design and grinding capabilities and is available exclusively with Ti-NAMITE-A, the most abrasive resistant coating for wear resistance, avoiding builtup edge and increasing tool life.

Related Glossary Terms

  • 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.

  • chatter


    Condition of vibration involving the machine, workpiece and cutting tool. Once this condition arises, it is often self-sustaining until the problem is corrected. Chatter can be identified when lines or grooves appear at regular intervals in the workpiece. These lines or grooves are caused by the teeth of the cutter as they vibrate in and out of the workpiece and their spacing depends on the frequency of vibration.

  • grinding


    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

  • pitch


    1. On a saw blade, the number of teeth per inch. 2. In threading, the number of threads per inch.

  • 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.
