Kennametal Introduces Chamfering Solutions and New Grade for KSEM Drills
(Latrobe, Pennsylvania, USA) -- Kennametal has introduced new chamfering rings, a spotting drill with built-in chamfering capabilities and grade KC7315 for its KSEM line of modular carbide drills. The new chamfering ring can produce chamfers up to 1.5 mm. The key advantage of the new chamfering ring and spotting tool is that they can be used to drill and chamfer in a single operation, reducing cycle time as well as tooling costs and inventory. These new products significantly add to the capabilities of the KSEM line, which already offers up to 10 times higher productivity than conventional high speed steel drills and 30% to 50% higher tool life than existing carbide drills. "The new chamfering rings and spotting drills will help our customers achieve the highest possible productivity and tool life on drilling operations from 0.5 to 1.5 inches," said Chet Parzick, Senior Product Manager for Kennametal.
The chamfering ring can be positioned anywhere along the body of the KSEM drills in order to control hole depth. A typical application is to prepare a hole for tapping in a single operation. The chamfering ring has two cartridges, each of which contains an insert with two cutting edges. Two grades are available for chamfering. Grade KC7215 is a physical vapor deposition (PVD) titanium aluminum oxide coated grade designed for machining low-carbon and alloy steels and cast irons. Grade KC7015 is a PVD titanium nitride coated grade designed for stainless steel and nonferrous materials. The rings are recommended for use in producing chamfers up to 1.5 mm by 1.5 mm.
The new spotting tool incorporates the chamfering inserts directly into the cutter body. The KSEM blade has a 150 degree included angle, compared to the 140 degree angle found in other KSEM drills, which provides better centering for the following cut. The spotting tool is also available without chamfering inserts and both styles are offered in the same 0.500 inch to 1.575 inch and 12.5 mm to 40 mm diameters as the rest of the KSEM line.
The other addition to the KSEM modular drilling line is that blades are now available in new grade KC7315, which has an advanced PVD titanium aluminum oxide coating and an improved substrate for higher performance in machining alloy steels, such as 4140 steel. The KSEM line features the HP geometry which offers a higher positive rake angle to improve penetration rates on Z-axis thrust limited machines and a patented sculptured edge (SE) drill point that cuts faster by avoiding the deformation generated by conventional drills. KSEM is also the only modular drill system with a blade locking mechanism that is fully contained within the drill body, avoiding the potential for damage from chips. Besides the spotting drills mentioned above, KSEM drills are available in lengths of 3, 5, 7, and 10 times the hole diameter.
