New Line of PCD Tools for higher productivity

Kennametal tools

Polycrystalline diamond round tools, available with short lead times, enable, high efficiency aluminum machining, and has been made available by Kennametal Inc.
The new line of PCD round tools for aluminum machining 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 aluminum alloys and are available with very short lead times.
The new PCD round tools line enables customers to machine aluminum significantly faster, for greater productivity on the shop floor.

In drilling and reaming operations, these tools consistently perform at cutting speeds of up to 900 m/min (3,000 SFM).   Milling operations can be performed at an incredible 6.000 m/min (20,000 SFM)—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 0,1–0,8 μm (0.0025–0.02 μ-in) is achievable – far superior to conventional carbide tooling.

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

The offering at a glance

The line of PCD end mills features 6 to 50 mm diameter tools and Cutting depths up to 50 mm. There’s
Center-cutting, roughing, and finishing geometries and Various rake angles.

The PCD drill offering features 6 to 20 mm diameter in 0.5 mm increments and Up to 5 x D in Inch and metric sizes

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

The PCD round tools can also be requested as custom solutions to fit specific customer needs while still maintaining short lead times.

Kennametal is leveraging its decades of experience with PCD tooling in the automotive industry to make this technology readily available to any manufacturer looking for a cost-competitive and highly productive solution for aluminum machining

With over 80 years experience as an industrial technology leader, Kennametal Inc. delivers productivity to customers through materials science, tooling and wear-resistant solutions.
