BB Chamfer End Mill

45° Chamfer End Mill – Milling & Chamfering in One Tool.
Multi-function 45° chamfering end mills for drilling, side milling, and deburring. Carbide/TiAlN coating. For steel, aluminum, and plastics.
3-in-1 Function: Combines drilling (depth-diameter ratio ≤3), chamfering (45°), and side milling in a single tool

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

Premium Material: Solid carbide body with TiAlN coating for heat resistance (up to 800°C)

Precision Design: ≤0.01mm runout tolerance for burr-free chamfers and smooth side walls

Efficiency Boost: Eliminates tool changes, reducing machining time by 30%

Why Choose This Tool?

✅ Efficiency: Perform two operations without tool changes

✅ Cost Savings: One tool replaces two, reducing inventory needs

✅ Precision: Ground flutes ensure consistent 45° chamfers

✅ Durability: Carbide substrate withstands high-speed machining

Applications:

Deburring hole edges after drilling

Creating precise bevels on component edges

Edge chamfering on mold and die components

Surface milling and edge finishing in one setup

Chamfer at 45 Degrees

Made From Ultra-Fine Grain Carbide Rod Stock

Manufactured from micro-grain carbide blank, offering superior wear resistance and stability—designed as a dedicated end mill for high-hardness and high-speed machining applications

Micro-Grain Nano-Coating

Nano high-temperature wear-resistant composite coating; multiple surface treatment technologies are combined to enhance the protective capability of the coating for end mills.

Complete Specifications

Versatile cutting performance for a wide range of materials, including steel and aluminum.

Sharp Rake Angle Enables Fast Cutting

Sharp and wear-resistant rake angle reduces cutting heat, solving tool sticking at the source. The edge blunt processing improves tool surface finish, while enhancing rigidity, sharpness, and ensuring smoother cutting.

Universal Round Shank Design

Anti-slip design at the tail, close to the chuck
Tighter grip without slipping

Applicable Equipment

Suitable for engraving machines, CNC machining centers, etc.
