Reduced Shank HSS Drill Bits 13–25mm | Large Diameter Metal Drilling | Abracs

Reduced Shank HSS Drill Bits (13–25mm) for metal

Need larger drill diameters but only have a standard 10mm or 13mm chuck? Reduced shank HSS drill bits let you drill 13–25mm holes without stepping up to specialist tooling. Ideal for workshop, fabrication, maintenance and site use where you need bigger holes in steel and non-ferrous metals.

Key benefits

• Reduced shank design fits standard 10mm / 13mm chucks (varies by diameter)
• HSS construction for dependable cutting and long service life
• Twist flute geometry for consistent swarf removal and smoother drilling
• Large diameter range for brackets, plate, fabrication work and repairs

Suitable materials

• Mild steel and general steels
• Cast iron
• Aluminium, copper and non-ferrous metals

How to get cleaner holes

• Use cutting oil on steel and thicker sections
• Start with a pilot hole (especially above 18mm)
• Use slower RPM as diameter increases and clear swarf regularly
