100mm*100mm TCT Annular Cutter 31.75mm Weldon Shank | Custom Non-Standard, Max Cutting Diameter 250mm

Product Overview

Our TCT Annular Cutter (Tungsten Carbide Tipped Core Drill) delivers fast, precise hole-making for heavy-duty metal machining. Widely adopted in steel structure fabrication, bridge engineering, shipbuilding, rail transit, power engineering, mechanical maintenance and heavy industry workshops, this cutter excels in both factory batch production and on-site field drilling.

Our standout capability: Custom non-standard sizes available. Our TCT annular cutters can be manufactured up to a maximum cutting diameter of 250mm, to solve your special large-hole drilling challenges that standard cutters cannot handle.

Material Advantage:

Cutter Body: H11 Hot Work Tool Steel

H11 matrix has outstanding toughness and thermal fatigue resistance. It stays stable under repeated high-temperature cutting, less prone to deformation during continuous heavy-load drilling and extends cutter body service life.

Carbide Tips: K30 Grade Tungsten Carbide

K30 carbide features high hardness and superior wear resistance. Tips are firmly brazed onto the cutter body, maintaining stable cutting performance under high speed and heavy load, greatly reducing chipping risk.

Key Features

High Drilling Efficiency

Annular cutters only cut the edge of the hole instead of removing full core material. Less cutting force, faster penetration and lower power demand for magnetic drills.

Clean & Accurate Holes

Sharp carbide cutting edges create smooth hole walls with minimal burr, ensuring consistent dimensional tolerance for assembly.

Standard Weldon Straight Shank

31.75mm standard Weldon shank, compatible with most mainstream magnetic drilling machines globally, stable clamping without slipping under heavy cutting.

Custom Non-Standard Size Service (Unique Strength)

Beyond standard sizes, we produce bespoke annular cutters for special projects. Maximum available cutting diameter reaches 250mm. Custom diameter, cutting depth, shank style are supported upon drawings or requirements.

Long Service Life

Combination of tough H11 body and wear-resistant K30 carbide tips balances impact resistance and wear performance for prolonged working cycles.

Application Fields

• Steel structure manufacturing & installation
• Bridge, tunnel and construction engineering
• Shipbuilding and marine engineering
• Rail transit & railway projects
