BB 3mm Shank End Mill — Ball Nose & Flat | D0.5–3mm

Solid carbide end mills with 3mm shank diameter, available in flat and ball nose types. Designed for precision CNC engraving, small-part milling, and fine detail machining. Two series cover steel, stainless steel, aluminum, and non-ferrous metals. Cutting diameter range: D0.5 – D3 mm.

Series Overview

Shank diameter: D3 mm | Cutting diameter: D0.5 – D3 mm | Overall length: 50 / 75 / 100 mm

BF2055 — Sharp and Durable, Fast Cutting

Optimized edge geometry balances sharpness and edge strength. Large core diameter design improves anti-vibration performance and reduces deflection during high-speed cutting of aluminum alloy, copper alloy, acrylic, and wood.

BB2055 — Durable and Long-Lasting

Flat end mill suitable for a wide range of materials including stainless steel, die steel, cast iron, aluminum alloy, copper, and carbon steel. Available in ball nose configuration for 3D contouring and curved surface machining.

Suitable Processing Methods

— Flat surface milling and side milling
— Slot cutting and U-groove machining
— Spot facing and step milling
— 3D contouring and curved surface finishing (ball nose)
— Suitable for CNC engraving machines and machining centers with ER collet chucks

Large Core Diameter — Rigidity and Chip Clearance

Large core diameter design improves tool rigidity and shock resistance, reducing the risk of tool breakage. Combined with optimized flute geometry for smooth chip evacuation and improved milling efficiency.

Reinforced Edge — Chipping and Breakage Resistance

Edge honing process strengthens the cutting edge, reducing chipping caused by micro-notches. Burr-free edge finish reduces tool change frequency and improves surface quality on finished parts.

Micro-Grain Carbide Substrate

Manufactured from ultra-fine grain tungsten carbide rod stock. Offers improved wear resistance, high hardness, low thermal expansion coefficient, and corrosion resistance — extending tool life in precision small-diameter applications.

Advanced PVD Coating

Applied via PVD process for a balanced, uniform coating. Provides high-temperature resistance and corrosion resistance, improving surface hardness and extending tool life in both dry and semi-dry cutting conditions.

Round Shank — Secure Clamping

Standard D3mm round shank with chamfered end. Compatible with ER collet chucks and standard tool holders. Secure clamping without slipping, improving vibration resistance and cutting stability at high speeds.
