Technical data:

Item	Details
Material	Mainly high-speed steel like M2, M2Al, M35 (with 5% cobalt) and M42; M35/M42 variants offer better heat and wear resistance for tough materials.
Key Dimensions	Cutting diameter ranges from 12mm to 65mm (some models up to 100mm); common cutting depths are 25mm, 35mm, 50mm, 75mm and 100mm. The standard Weldon shank diameter is 19mm (or 19.05mm), matching most magnetic drill arbors.
Structural Features	Often adopts multi-cut geometry; some models have 12 flutes for efficient chip removal. Cutters ≤40mm usually have an extra shank hole for compatibility with quick-change systems.
Surface Finish	Available in bright uncoated, TiN-coated, or TiAlN-coated options to enhance wear resistance and reduce cutting friction.
Applicable Equipment	Compatible with magnetic drills (e.g., Alfra, Hougen) and also fits vertical drills, radial drills, and milling machines via matching arbors.

Advantages

Secure & Stable Clamping: The Weldon shank’s double-flat design ensures firm grip, minimizing vibration during high-speed cutting and maintaining hole diameter accuracy.
Cost-Effective & Regrindable: Compared to TCT cutters, HSS versions have lower costs. They can be reground repeatedly after blunting, extending service life and reducing tool replacement expenses.
Efficient Cutting & Chip Removal: Optimized multi-cut geometry and fluted structure (e.g., 12 flutes) enable layered cutting, low friction, and smooth chip evacuation, avoiding clogging and improving cutting speed.
Broad Versatility: Suitable for drilling mild steel, stainless steel, cast iron, copper, aluminum and other metals. It works with various mainstream magnetic drills and drilling machines, widely used in steel structures, shipbuilding, and machinery manufacturing.
