Kennametal has introduced a new line of PCD round tools for aluminium machining that delivers up to 10 times higher productivity than carbide tooling. The new line of drills, reamers and end mills provides exceptional tool life and wear resistance even in very abrasive aluminium alloys and are available with very short lead times.

“Our new PCD round tools line enables our customers to machine aluminium significantly faster, for greater productivity on the shop floor,” says Michael Hacker, Product Manager, Kennametal.

“In drilling and reaming operations, these tools consistently perform at cutting speeds of up to 900m/min. Milling operations can be performed at an incredible 6m/min, far higher than non-PCD tooling.”

Long tool life, high productivity gains
With through-the-tool coolant capabilities and an MQL-ready interface, these PCD round tools are ideal for both rough and finish machining.

Extremely sharp cutting edges and low-friction rake surfaces eliminate concerns over built-up-edge. Low friction machining also produces superior surfaces in finishing operations, such as reaming. Surface roughness of Ra 0.1 to 0.8μm is achievable, far superior to conventional carbide tooling.

PCD grade KD1410 assures extended tool life and is particularly beneficial in the high silicon content aluminium used to make automotive parts like engine blocks or cylinder heads.

The line of PCD end mills features 6mm to 50mm diameter tools, cutting depths up to 50mm, centre-cutting, roughing and finishing geometries and various rake angles.

The PCD drill offering features 6mm to 20mm diameter in 0.5mm increments, up to 5 x D and is available in inch and metric sizes.

The PCD reaming portfolio offers 6mm to 20mm in diameter in 1mm increments and through and blind hole versions. For larger diameters up to 42 mm, the PCD modular reaming system with KST coupling is available.
