HSS&TCT Annular Cutters for Magnetic Drills

Annular Cutters – Faster, Cleaner Holes Than Twist Drills

BABOS annular cutters (also called core drills or broach cutters) cut only the material around the hole's circumference, removing a solid slug instead of grinding away the full hole. The result: 3–4× faster drilling, 50% less torque, and smoother, more accurate holes than twist drills — essential for steel fabrication, structural steelwork, shipbuilding, rail maintenance, and pipeline construction.

TCT or HSS? Choose the Right Cutter for Your Job

• TCT Annular Cutters (tungsten carbide tipped): For hardened steel, stainless steel, and high-volume production. Carbide tips stay sharp far longer and handle materials up to HRC 45+. Available in cutting depths from 25mm to 100mm, with diameters up to 65mm standard — custom sizes up to 250mm available on request.

• HSS Annular Cutters (M2 high-speed steel): The economical choice for general steel and mild steel work. M2 steel construction offers excellent toughness and value for maintenance and fabrication shops.

Shank Options for Every Magnetic Drill

• 19.05mm Weldon shank — the universal standard (3/4")

• Universal/straight shank — fits most quick-change chucks

• Fein Quick-IN 18mm shank — for Fein and compatible magnetic drills

FAQS

Q: What's the difference between TCT and HSS annular cutters?

 A: HSS cutters are cost-effective for mild and general steel. TCT cutters have carbide tips that cut faster and last much longer in hardened steel, stainless steel, and continuous production use.

Q: Which shank do I need for my magnetic drill?

A: Most magnetic drills use a 19.05mm (3/4") Weldon shank. Fein machines use an 18mm Quick-IN shank. If you're unsure, send us your drill model and we'll confirm.

Q: Can you make custom diameters or depths?

A: Yes. Custom diameters up to 250mm and special cutting depths are available as OEM/ODM orders.
