Description

SQUARE END MILL · CARBON STEEL · WHOLESALE

Product Overview

This carbide square end mill is designed for slotting, side milling,
shoulder milling and flat-surface machining of carbon steel, mild steel,
low-alloy steel and cast iron up to HRC55.

An ultra-fine carbide substrate, AlTiN nano-composite coating and
precision-ground square cutting profile support stable cutting,
smooth chip evacuation and consistent performance in repeat production.

✓ Up to HRC55
✓ 2F / 4F / Custom
✓ AlTiN Coating
✓ OEM & Private Label

Recommended Machining Applications

The flat-bottom cutting profile makes this tool suitable for common
steel milling operations requiring flat surfaces, straight walls
and stable shoulder machining.

01

Slotting

Suitable for machining full-width slots in carbon steel
and general steel materials.

02

Side Milling

Supports stable peripheral cutting and straight-wall machining.

03

Shoulder Milling

Designed for square shoulders and applications requiring
controlled wall and bottom geometry.

04

Flat-Surface Machining

The square cutting profile supports flat-bottom and
general surface milling operations.

Square End Mill Geometry and Performance

The carbide material, coating, cutting geometry and edge preparation
are designed to balance cutting sharpness, tool strength and wear resistance.

01

Ultra-Fine Carbide Substrate

Made from ultra-fine carbide with a grain size below 0.8 μm
and 10% cobalt content, providing a stable balance of
cutting-edge strength, toughness and wear resistance.

02

AlTiN Nano-Composite Coating

The high-aluminum AlTiN coating offers oxidation resistance,
red hardness and wear resistance at operating temperatures
up to approximately 1100°C.

03

6° Positive Rake Angle

The positive rake geometry helps reduce cutting resistance
and supports smoother entry into carbon steel and
general steel workpieces.

04

35° Helix Design

The 35° helix supports smooth chip evacuation and stable cutting
during slotting, side milling and shoulder machining.

05

Dual-Margin Peripheral Edge

The dual-margin design improves tool guidance and cutting stability
during peripheral milling and repeat machining operations.

06

Controlled Edge Preparation

Fluid blasting and automated rubber-diamond polishing help remove
microscopic burrs and control edge preparation within ±0.003 mm.
