Description
Overview:
The BlueSpot Tools HSS Step Drill 4-22 mm (approx. 0.16-0.87 inches), MPN 32050, is a conical step bit for accurate hole enlargement with a single cutter. Made from high-speed steel (HSS) with a titanium coating, it delivers strong cutting performance and good wear resistance on metals and plastics. The 2 mm step increments help you size holes precisely without changing bits. It is suitable for corded and cordless hand drills as well as drill presses, making it useful on site or in the workshop. Use it on aluminium, brass, copper, plastics, mild steel, and timber for clean, round holes. Reliable for trades and DIY, it reduces setup time and supports controlled drilling in sheet, plate, and non-ferrous materials.
Key Features:
- High-speed steel body for strength and consistent cutting in demanding tasks
- Titanium coated to reduce friction and heat, helping maintain edge sharpness
- 4-22 mm range (approx. 0.16-0.87 inches) covers common hole sizes with one tool
- 2 mm step increments for precise, repeatable sizing and tidy finishes
- Suitable for aluminium, brass, copper, plastics, mild steel, and wood
- Works with standard drill chucks in cordless drills, corded drills, and drill presses
- Step geometry helps produce round holes and can chamfer or deburr as you enlarge
- Efficient for thin sheet and panel work, reducing bit changes and downtime
- Smooth cutting action helps minimise grabbing when used at appropriate speeds
- Long service life when used with steady feed and cutting fluid on metals
Typical Applications:
Electrical and plumbing knockouts, control panels, brackets, junction boxes, automotive and bodywork repairs, HVAC ducting, trailer and enclosure fabrication, kiosks and signage, machine guards, and general workshop or site drilling where multiple hole sizes are required without frequent bit changes.
