HEULE'S GH-K TOOL

HEULE, a world leader in tool development, introduces GH-K tooling which provides precision chatter-free countersinks from 3mm – 45mm (0.118” to 1.771”) in a wide range of materials. Engineered with a positive geometry for high shear cutting action, it features carbide blades for machining cast iron, steel, aluminum, and non-ferrous materials, with optional HSS-Cobalt coated blades for steel and stainless-steel applications. Three-blades tools supplied for manual or CNC applications; single-bladed tools for all machining centers. Regardless of the number and composition, replaceable, re-grindable blades make GH-K an economical choice for many machining operations. All inserts are ground as a set at serialize to minimize deviation, so they cut at the same time, and minimize chatter, while enhancing surface finish. These unique tools are suitable for conventional milling of chamfers around the perimeter of larger holes or entire parts. GH-K Tooling available from stock in sizes from 3-45 mm (0.118 – 1.771 inches) at 60, 82, 90, and 100-degrees. How it works As the tool is fed into the part, the blades start cutting once the tip contacts the material. The operator continues to feed the tool until the desired countersink size is achieved, then rapidly retracts the tool. The GH-K’s shallow radial clearance ensures precision and chatter-free operation, although controlled feed rates may be necessary. Shims can be added to adjust the tool’s performance for more aggressive feed rates.
