Sutton reduced-shank and special-purpose drills — including auger bits, core drills, and large-diameter reduced-shank twists — extend the capacity of standard drill chucks or drilling machines beyond their normal diameter range.

Where this product is used

Used where the drill diameter exceeds the standard chuck capacity, or where a specialised hole profile is required in timber, composite, or metal materials.

• Large-diameter drilling in steel plate with a 13 mm reduced shank in a standard keyed or keyless chuck, keeping the drill centred without a larger chuck or machine.
• Auger drilling in timber framing and structural wood for cable runs, plumbing, and bolt holes on construction sites.
• Deep-hole drilling in stainless or structural steel using reduced-shank formats to access harder-to-reach machine setups.

Key specifications

Selecting the right option

Reduced shank drills require a solid chuck grip and slow speeds (typically 350 RPM or less) — confirm your machine and chuck rating before use. For auger bits, ensure the shank format matches your power tool. Always pilot-drill large-diameter holes for better accuracy and reduced thrust load.
