KY TOOLS / END MILLS
End Mills by Material Series
General Series
TiSiN PVD-coated carbide end mills for general milling, with square, ball nose, corner radius, long-neck and roughing profiles.
Hard Series
Carbide end mills for hardened and tool steel applications, including HRC50–65 machining. Compare 2-, 4- and 6-flute profiles and roughing options.
SUS & Titanium Series
End mills for SUS stainless steel and titanium alloys. Explore the existing ZrN-coated range and standard order codes.
Non-Ferrous Metal Series
R-TAC coated carbide end mills for aluminum, copper, CFRP and other non-ferrous or non-metallic materials. Compare five profiles.
Graphite Series
Diamond-coated end mills for graphite electrode machining. Choose the geometry and reach for your production requirements.
KY TOOLS / Ø2–20 mm
Reamers
Straight Flute Carbide Reamers
For blind and through holes. A versatile starting point when both hole types appear on the same purchasing list. Confirm stock allowance and chip clearance for each application.
Right-Hand Spiral Carbide Reamers
Recommended for blind holes; also suitable for through holes. The right-hand spiral helps return chips towards the entry, where bottom clearance and coolant access need careful review.
Left-Hand Spiral Carbide Reamers
For through holes. The left-hand spiral directs chips towards the exit. Keep exit clearance available; left-hand spiral describes the flute helix, while cutting remains right-hand.

25 Years of Precision
Manufacturing
What started as a small workshop with 10 machines in Changzhou has grown into a specialist carbide tooling manufacturer trusted by engine builders, mold shops, and precision manufacturers across Europe, North America, and beyond.
Our focus has always been deep-hole internal coolant drills and difficult custom carbide tooling — the applications where geometry precision and coating quality matter most.
