HRC65 Solid Carbide Corner Radius End Mill Overview
The HRC65 solid carbide corner radius end mill is engineered for stable profiling, pocket finishing and semi-finishing in hardened steel, heat-treated steel, die steel and mold steel. Its 4-flute geometry provides a rigid core and consistent cutting engagement, while the corner radius reinforces the transition between the end and peripheral cutting edges. Ultra-fine-grain carbide and heat-resistant coating options support wear resistance, edge stability and repeatable surface quality in demanding mold and high-hardness machining.
Key Product Advantages
Reinforced Corner
The corner radius improves edge strength compared with a sharp-corner square end mill and supports controlled part fillets.
Rigid 4-Flute Core
Four cutting edges and a rigid core support stable side milling, profiling and finishing in hardened steel.
Heat-Resistant Coating
Application-matched coatings help resist oxidation, abrasive wear and high cutting temperatures.
Standard & Custom Supply
Diameter, radius, flute length, shank, overall length, geometry and marking can be reviewed by drawing.
Recommended Applications
Recommended for profile milling, pocket finishing, contour machining, corner finishing and controlled-engagement semi-finishing in rigid CNC machining conditions.

FAQ sur les produits et leurs applications
Selection and application guidance for hardened-steel, die-steel and mold-steel machining.
What materials is this HRC65 corner radius end mill designed to machine?
It is primarily configured for hardened steel, heat-treated steel, die steel, mold steel and tool steel. Suitability for stainless steel, titanium alloys or other materials should be reviewed according to the exact grade, hardness, operation, tool size and machining conditions.
Does HRC65 mean that every tool can machine steel at exactly 65 HRC?
HRC65 describes the product-series positioning and its upper target range under selected machining conditions. Actual suitability depends on the steel grade, operation, cutting diameter, corner radius, cutting data, tool overhang, holder runout, machine rigidity and coolant strategy. Application details should be reviewed before machining near the upper hardness range.
What operations are suitable for the corner-radius design?
The corner-radius geometry is suitable for profile milling, pocket finishing, contour machining, corner finishing and controlled-engagement semi-finishing. The reinforced corner provides greater edge strength than a sharp-corner square end mill while producing a defined part fillet.
How should the corner radius be selected?
Select a corner radius equal to or smaller than the required component fillet. The final R value should also be reviewed according to the cutting diameter, machining allowance, required edge strength and finished-part geometry.
Why does this end mill use a four-flute configuration?
The four-flute geometry provides a rigid tool core and more cutting contacts per revolution. This supports stable profiling and finishing in hardened steel when radial engagement, axial depth, chip evacuation and machine rigidity are correctly controlled.
Which coating should be selected for hardened-steel machining?
AlTiN, TiAlN, TiSiN, AlTiSiN or another application-specific coating can be selected according to the steel grade, actual hardness, cutting temperature and machining conditions. The coating should be matched with the carbide grade and cutting-edge preparation rather than selected by color alone.
FAQ sur les commandes et la personnalisation
Information for distributors, tooling brands and customers requesting standard or drawing-based configurations.
What reference sizes are available?
The reference size matrix covers selected cutting diameters from Ø1 to Ø12 mm with multiple corner-radius, shank-diameter and overall-length combinations. Final availability should be confirmed by cutting diameter, radius, flute length, shank diameter, overall length and coating.
Can non-standard dimensions or geometry be manufactured?
Yes. Cutting diameter, corner radius, flute length, neck geometry, shank diameter, overall length, helix angle, edge preparation and coating can be reviewed according to the drawing and machining application. Custom dimensions and tolerances are confirmed before production.
Can I order samples before placing a bulk order?
Yes. Sample orders and custom-size trials can be reviewed according to the required dimensions, carbide grade, coating and quantity. Please contact us to confirm sample availability, production cost and delivery charges.
What is the lead time?
In-stock standard configurations can normally be dispatched within 1–3 working days. Production time for custom dimensions, special corner radii, application-specific coatings, laser marking or private-label packaging is confirmed after the specification and order quantity have been reviewed.
Proposez-vous le marquage OEM et le conditionnement sous marque de distributeur ?
Yes. Customer logos, tool codes, cutting dimensions, corner-radius values, hardness-series identification and batch numbers can be laser marked according to the available shank area. Custom labels, protective tubes and private-label packaging can also be supplied.
What information is required for an accurate quotation?
Please provide the workpiece material and actual hardness, cutting diameter, corner radius, flute length, shank diameter, overall length, machining operation, axial depth ap, radial engagement ae, coating preference, tolerance requirements and order quantity. A tool drawing or component drawing is recommended for custom projects.
