BB 45° Chamfer End Mill | Carbide Corner Chamfer Cutter | D3-12mm | 4 Series

BB Chamfer End Mill — 45° Corner Chamfer Milling Cutter

A solid carbide end mill with an integrated 45° chamfer edge, combining side milling, chamfering, and deburring in a single tool. Suitable for steel, stainless steel, aluminum alloy, and engineering plastics. Available in 4 series and diameters from 3 mm to 12 mm.

Key Features

3-in-1 Function: Side milling (depth-to-diameter ratio ≤3), 45° chamfering, and deburring in a single setup — no tool change required.

Wide Material Compatibility: Suitable for steel, stainless steel, aluminum alloy, and engineering plastics.

Solid Carbide Body with TiAlN Coating: Heat resistance up to 800°C; coating improves wear resistance and extends tool life.

Runout Tolerance ≤0.01 mm: Consistent 45° chamfer geometry and smooth side walls.

Anti-Slip Round Shank: Knurled tail section near the chuck for secure clamping without slipping.

45° Chamfer Profile

This product features a chamfered cutting edge (45°), as shown in the left diagram below. Suitable for edge chamfering and hole-entry deburring.

Micro-Grain Carbide Substrate

Manufactured from micro-grain carbide rod stock, offering improved wear resistance and dimensional stability. Recommended for high-hardness and high-speed machining applications.

Nano-Composite TiAlN Coating

Multi-layer nano-composite coating applied via PVD process. Improves surface hardness, reduces friction, and extends tool life in dry and semi-dry cutting conditions.

Series & Specifications

Four series available, each optimized for different cutting conditions:

Diameter range: D3 – D12 mm  |  Chamfer angle: 45°  |  Shank: round, standard tolerance

Sharp Rake Angle for Reduced Cutting Heat

Ground rake angle reduces cutting heat and minimizes built-up edge. Edge honing improves surface finish and cutting stability.

Anti-Slip Round Shank

Knurled tail section near the chuck provides a secure grip. Compatible with standard ER collet chucks and milling tool holders.

Applications

— Deburring hole edges after drilling
— Edge chamfering on mold and die components
— Precise bevels on part edges
— Surface milling and edge finishing in a single setup
— Suitable for CNC machining centers and engraving machines
