Customized 8mm Pitch Triangle Tooth Gear Broach

Customized 8mm Pitch Triangle Tooth Gear Broach — Precision Non-Standard Tool for Special Gear Profiles

Technical Requirements of 8mm Pitch Triangular Gear Broaches

The 8mm pitch triangle tooth gear broach is a custom-engineered cutting tool designed for precision machining of special or non-standard gear profiles. Each broach is produced according to the customer’s drawing, ensuring perfect tooth geometry, tight tolerance, and superior surface finish.

Manufactured from premium HSS or carbide materials and optionally coated with TiN, TiAlN, or AlCrN, this broach provides exceptional wear resistance, high strength, and extended tool life during continuous production.

Key Specifications:

Type: Non-standard customized gear broach

Tooth Form: Triangle (special profile)

Material: HSS M35 / M42 / Carbide (customizable)

Coating Options: TiN, TiAlN, AlCrN, or black oxide

Application: Precision broaching for internal or external gears, automotive parts, hydraulic components, and industrial machinery

Advantages:

1. Fully customizable design based on drawing or 3D model
2. High accuracy for triangle, involute, or spline profiles
3. Stable cutting performance and reduced tool replacement cost
4. Ideal for mass production lines and precision machining workshops

Material:. The radial runout tolerance for each outer diameter of the broach is 0.03mm. The radial runout of the calibration tooth and its two adjacent cutting teeth must not exceed the outer diameter tolerance and must be aligned. Center hole size: B1.5 mm.
