Radius End Mill for Hardened Steel
EPDREH-TH3
EPDRH-TH3
Small-radius deep-milling radius end mill for hardened steel
DC8mm to 12mm added to the 4-flute lineup!TH3 Coating benefits and unique cutting edge profile enables long-life/high-accuracy milling of hardened steel.
Features of EPDR(E)H-TH3
Corner radius precision guaranteed for high-accuracy milling
TH3 Coating for milling hardened steel
Tool design optimized for high-accuracy milling
EPDREH-TH3 2 Flutes φ0.2～φ1 ［ 53 Items］
(Corner Radius R0.02～R0.2)4 Flutes φ1～φ6 ［266 Items］
(Corner Radius R0.02～R1)EPDRH-TH3 4 Flutes φ8～φ12 ［26 Items］
(Corner Radius R0.2～R2)Task We need high-precision milling. But high-accuracy milling requires measuring the actual tool diameter.And diameter corrections take time. Point The corner radius of Evolution type uses the tool centerline as its datum independent of the tool diameter. This allows high-accuracy milling compared to conventional tools, even when using nominal diameters.
