HRC55 4-Flute AlTiN-Coated Corner Radius End Mill Overview
This HRC55-series 4-flute solid carbide corner radius end mill is designed for stable roughing, semi-finishing and contour milling in carbon steel, alloy steel, tool steel and selected pre-hardened steel. Its reinforced corner radius provides greater edge strength than a sharp square corner while retaining a flat-bottom cutting profile. The four-flute geometry increases cutting-edge engagement and supports productive side milling, profiling and pocket machining, while the AlTiN coating improves heat and wear resistance under steel-milling conditions.
Key Configuration
Reinforced Corner Radius
The radiused corner reduces local edge stress and chipping risk while maintaining a usable flat-bottom profile.
Four-Flute Cutting Geometry
Four cutting edges support productive side milling, profiling and semi-finishing with stable engagement.
AlTiN for Steel Milling
The heat-resistant coating helps protect the cutting edge during dry, air-blow or controlled-coolant machining.
Key Product Advantages
Stronger Corner
Improved corner strength compared with a sharp-edge square end mill.
Productive Engagement
Four flutes provide more cutting contacts per revolution for stable steel milling.
Thermal Protection
AlTiN supports wear resistance under elevated cutting temperatures.
Steel-Series Carbide
Micro-grain carbide is matched to general and pre-hardened steel applications.
Recommended Milling Operations
The corner-radius profile is particularly useful where a sharp corner is unnecessary and improved tool-edge reliability is preferred.

Additional Product Details
Corner Radius End Mill Application Guidance
- Radius Selection: Select an R value equal to or smaller than the required part fillet.
- Side Milling: Use appropriate radial engagement to benefit from the four-flute geometry and control cutting temperature.
- Pocket Machining: Confirm center-cutting and entry capability before plunging or helical interpolation.
- Toolholding: Use a low-runout holder and minimize unnecessary overhang, especially for small DC and small R sizes.
- Chip Control: Use air blow or a suitable coolant strategy to prevent chip recutting in enclosed pockets.

Product & Application FAQs
Selection and application guidance for steel milling with a reinforced corner-radius profile.
What materials is this HRC55 corner radius end mill designed to machine?
It is primarily designed for carbon steel, alloy steel, tool steel, mold steel and selected pre-hardened steel. The exact suitability and cutting parameters should be confirmed according to the workpiece grade, hardness, milling operation and machine rigidity.
What is the advantage of the corner-radius cutting profile?
The corner radius reinforces the transition between the end cutting edge and peripheral cutting edge. This helps reduce local cutting stress and chipping risk compared with a sharp-corner square end mill while retaining a flat-bottom cutting profile for pockets, steps and contour features.
How should I select the correct corner radius?
Select a cutter radius equal to or smaller than the required internal fillet of the workpiece. A larger radius generally provides greater corner strength, but the tool cannot produce an internal corner smaller than its own R value. Please provide the component drawing when the fillet specification is critical.
What operations are suitable for the 4-flute corner-radius design?
The tool is suitable for side milling, pocket machining, contour milling, roughing and semi-finishing in steel. The four-flute geometry provides more cutting contacts per revolution and supports productive machining when chip evacuation and tool engagement are properly controlled.
Can this 4-flute end mill be used for full-width slotting?
Selected configurations can perform slotting, but the four-flute design provides less chip space than a two-flute cutter. Use reduced cutting parameters, reliable chip removal and appropriate axial engagement for full-width slotting. Center-cutting and plunge capability should be confirmed for the selected size.
Why is AlTiN coating used for this steel end mill?
AlTiN coating provides heat and wear resistance for steel-milling applications. It helps protect the cutting edge under elevated cutting temperatures and is suitable for dry machining, air-blow machining and selected controlled-coolant conditions.
Does HRC55 mean every tool can machine steel at exactly 55 HRC?
HRC55 describes the product-series positioning and upper application target under selected machining conditions. Actual suitability depends on the steel grade, tool diameter, corner radius, machining operation, engagement, tool overhang, holder runout and machine rigidity.
Ordering & Customization FAQs
Information for distributors, tooling brands and customers requesting standard or drawing-based configurations.
What standard sizes are available?
The reference size range covers selected cutting diameters from Ø1 to Ø12 mm with multiple corner-radius, shank-diameter and overall-length combinations. Final stock availability should be confirmed by cutting diameter, corner radius, flute length, shank diameter and overall length.
Can non-standard dimensions or corner radii be manufactured?
Yes. Cutting diameter, corner radius, flute length, reach, shank diameter, overall length, helix angle, cutting-edge preparation and coating can be reviewed according to the drawing and machining application. Final dimensions and tolerances are confirmed before production.
Can I order samples before placing a wholesale order?
Yes. Sample orders can be reviewed according to the required cutting diameter, corner radius, coating and quantity. Please contact us to confirm the available size, sample cost and shipping arrangement.
What is the lead time?
In-stock standard sizes are generally ready for shipment within 1–3 days. Lead time for customized or made-to-order tools is confirmed after reviewing the required dimensions, corner radius, coating, order quantity and packaging requirements.
Are OEM marking and private-label packaging available?
Laser marking, tool codes, custom labels, protective tubes and private-label packaging can be reviewed according to the available marking area, order quantity and confirmed packaging specification.
What information is required for an accurate quotation?
Please provide the workpiece material and hardness, cutting diameter, corner radius, flute length, shank diameter, overall length, machining operation, axial and radial engagement, coating requirement, dimensional tolerance and order quantity. A tool drawing or component drawing is recommended for custom projects.
