Description
Overview:
The Timco HSS Blacksmith Drill is a heavy‐duty, reduced‐shank metal drill bit made from high speed steel with a titanium nitride (TiN) coated cutting end for improved wear resistance. It has a 25.0mm cutting diameter and a 160mm overall length, with a 12.5mm shank featuring three flats for a secure grip in the chuck. Designed for reliable drilling in alloy steels, cast iron, non‐ferrous metals, and plastics, it suits both site and workshop use. The reduced shank allows large‐diameter drilling using standard 13mm keyed or keyless chucks on handheld drills, pillar drills, and similar machines. Built for consistent accuracy and long service life, this Timco bit delivers clean, controlled cutting on demanding tasks where precision and durability matter.
Key Features:
- 25.0mm cutting diameter and 160mm overall length for large, accurate holes
- High speed steel with TiN coating for increased hardness, reduced friction, and longer tool life
- 12.5mm reduced shank with 3 flats for a firm, slip‐resistant grip in 13mm chucks
- Suitable for alloy steel, cast iron, non‐ferrous metals (e.g. aluminium, brass), and plastics
- Engineered for precision and efficient drilling with stable guidance and neat finishes
- Works with corded and cordless drills, bench/pillar drills, and similar machines using 13mm chucks
- Robust build for repeated use in fabrication, maintenance, and installation work
- Helps reduce downtime and replacement costs through durable materials and coating
- Best practice: run at appropriate speeds for the material, use cutting fluid on metals, and pilot‐drill for accuracy
- Three‐flat shank reduces chuck wear and minimises bit spin under high torque
Typical Applications:
Drilling clearance and fixing holes in steel plate, angle, and box section; boring into castings; preparing holes for pipe runs, brackets, and guards; maintenance and repair on construction equipment, agricultural and garden machinery; fabrication of frames and gates; workshop and on‐site tasks involving non‐ferrous metals and plastics where a large, clean hole is required.
Also known as:
Blacksmith drill bit, reduced‐shank drill, large diameter HSS drill, metal drill bit, TiN‐coated HSS drill, 3‐flat shank drill, step‐down shank drill, workshop metal drill.
