Description
Overview:
The Timco HSS Blacksmith Drill is a reduced-shank metal drilling bit designed for accurate, repeatable hole making in tougher materials. Made from high-speed steel (HSS) and coated with titanium nitride for added wear resistance, it delivers good performance under continuous use. It features a 15.5mm cutting diameter and a 160mm overall length, with a 12.5mm three-flat shank for a secure grip in standard 13mm chucks. Suitable for corded or cordless hand drills, pillar drills and drill presses, it helps achieve clean holes in steel and other common engineering materials. Ideal for site work, fabrication, maintenance and workshop tasks where a larger hole size is needed without requiring a large-capacity chuck. Manufacturer reference: BS155.
Key Features:
- HSS construction for strength, hardness and heat resistance
- Titanium nitride coating for improved wear resistance and extended tool life
- 15.5mm cutting diameter and 160mm overall length for versatile hole sizing
- 12.5mm three-flat shank prevents chuck slippage and improves torque transfer
- Fits standard 13mm chucks on handheld and bench drills
- Reduced shank allows larger holes to be drilled with smaller-capacity tools
- Suitable for alloy steel, cast iron, non-ferrous metals and many plastics
- Good concentricity for cleaner holes and reduced vibration
- Simple to fit and remove; can be re-sharpened by a competent user
- Timco brand part, MPN BS155
Typical Applications:
Useful for drilling clearance and bolt holes in plate, angle, box section and brackets; maintenance and repair tasks on machinery and plant; site fabrication, metalwork and agricultural repairs; producing larger-diameter holes where a reduced shank is required for standard chucks; workshop projects involving common engineering metals and plastics.
Also known as:
Reduced shank drill bit, blacksmiths drill bit, 3-flat shank drill, HSS metal boring bit, large-diameter HSS drill, pillar drill bit, fabrication drill, TiN-coated HSS drill.
