Stainless Steel End Mill Profiles
Square, ball nose and corner radius end mills cover flat-bottom features, curved surfaces and radiused corners in stainless steel parts.
Carbide Square End Mill
For slots, side walls, pockets, shoulders and dynamic toolpaths requiring a flat-bottom profile.

Performance in Stainless Steel Machining
Stainless steel can work-harden, retain heat near the cutting zone and form ductile chips. The cutting geometry combines chip space at the cutting end with additional core support behind it.
52% / 70% dual core
The smaller front core increases flute space; the secondary core adds rigidity behind the cutting zone.
8° rake and 45° helix
Positive rake and high helix geometry support a cleaner cutting action and controlled chip flow.
88° / 92° end-tooth division
Unequal end-tooth division changes the timing of cutting-edge engagement to help reduce vibration.
Carbide and AlCrN Coating
The substrate and coating work with the cutting geometry to manage edge wear during stainless steel machining.
Ultra-Fine Carbide
Below 0.6 μm · 12% cobalt
The carbide substrate combines wear resistance with toughness at the cutting edge.
AlCrN Coating
Balzers AP AlCrN
A heat-resistant coating for stainless steel cutting conditions.
Cutting Conditions
The stainless steel grade and material condition affect the starting speed, feed and engagement.
Tool reach
The shortest reach that clears the feature helps limit deflection.
Chip evacuation
Flute space and coolant access matter in enclosed slots and deep pockets.
Engagement
Consistent cutting load helps avoid rubbing and sudden changes in tool pressure.
The range supports semi-finishing, finishing and dynamic milling. Cutting parameters should match the tool dimensions, machine setup and workpiece condition.
Carbide End Mill Manufacturing at ZHY
ZHY supplies standard and custom solid carbide end mills to CNC machining companies, distributors and OEM customers. Our factory is equipped for tool grinding, edge preparation, coating and inspection.
Grinding and Edge Preparation
Five-axis tool grinding controls flute and profile geometry. Fluid blasting and automated polishing prepare the cutting edges for coating.
In-House Coating
Our coating equipment supports carbide tool production at our factory. Coating specifications are agreed with the tool and machining requirements.
Tool Profile Inspection
HELICHECK PLUS measures tool profiles. Optical and appearance inspection support dimensional and surface checks.
Custom Dimensions and OEM Supply
Diameters, cutting lengths, shanks, overall lengths, corner radii and flute configurations can be manufactured to specification. Customer marking and private-label packaging are available for repeat orders.
Custom Tooling →Stainless Steel End Mill FAQ
What information is needed for a stainless steel end mill quotation?
For a stainless steel end mill quotation, ZHY needs the cutter profile, diameter, cutting length, shank diameter, overall length and quantity. Include the corner or ball radius where applicable. A dimensioned tool drawing can provide these details.
Should I use a 2-flute or 4-flute end mill for stainless steel?
Both 2-flute and 4-flute end mills can machine stainless steel. Two flutes provide more chip space; four flutes provide more cutting edges and a larger supporting core for a comparable tool design. ZHY can manufacture either configuration, with the choice based on engagement, chip evacuation and the required finish.
What coating does ZHY use on its stainless steel end mills?
ZHY uses Balzers AP AlCrN coating on this stainless steel end mill range. The coating provides heat and wear resistance. Tool geometry, chip evacuation and coolant delivery remain important to cutting performance.
Can ZHY make stainless steel end mills in custom dimensions?
ZHY manufactures stainless steel end mills with custom diameters, cutting lengths, shank diameters, overall lengths and corner radii. A tool drawing or a dimensioned specification can be used for a quotation.
What information does ZHY need to recommend an end mill for my stainless steel part?
ZHY needs the stainless steel grade and material condition, machining operation, feature dimensions and required tool reach to recommend an end mill. A part drawing, machine details, coolant method and required quantity help establish a suitable configuration.
Does ZHY supply stainless steel end mills with customer branding?
ZHY offers customer logo marking and private-label packaging for stainless steel end mills. Marking, labels and packaging details can be specified with the order.
Does ZHY have its own coating equipment?
Yes. ZHY has in-house coating equipment at its factory. The coating specification for an order is agreed together with the tool geometry, workpiece material and machining application.
