Name: 10mm 4-Flute R0.5mm TiSiN Corner Radius End Mill for HRC55
Brand: Solid Carbide Direct
SKU: SCD-CREM-TISIN-4F-D10-R05-L55
Price: 128.86 USD
Availability: InStock

TiSiN-coated 4-flute corner radius end mills combine the rigidity of a square end mill with corner geometry that reduces stress concentration and micro-chipping on hardened surfaces up to HRC55. The corner radius distributes cutting load across a wider arc at entry, dramatically extending tool life versus sharp-corner tools in steel and stainless steel shoulder milling and semi-finish passes. TiSiN hardness > 3,500 HV resists abrasion at continuous contact conditions.

R0.5mm Corner Geometry

Industry standard fillet — most common CNC pocket and shoulder radius

▸Longest tool life in class for shoulder milling and pocketing
▸Matches ISO standard pocket corner specification R0.5mm
▸Reduces cutting forces by ~20% vs sharp corner in hardened steel
▸Available in full standard size range including long-reach variants

Radius Selection Tip: R0.5mm is the most universal specification. In HRC55 steel, it provides the best balance of fillet feature accuracy, tool life, and chatter resistance. Recommended for all new mould base and structural component programmes unless design specifically requires R < 0.5mm.

ø10mm Applications

10mm TiSiN — Where This Tool Fits

▸Automotive component shoulder milling
▸Pump body and valve pocket features
▸Gearbox cover profiling
▸Large mould runner channel machining

Machining Tip: ø10mm is the production sweet spot for corner radius end mills. In HRC55 steel, radial engagement can be 30–50% of D for profiling, with DOC up to 1×D for semi-finish passes. The corner radius reduces chatter significantly at this diameter.
