Halls CC 1 CONECUT High Speed Steel Sheet & Tube Drill 6-20mm | CC1

Halls CC1 CONECUT HSS sheet & tube drill bit (6–20mm range, 10mm chuck)

The Halls CC1 CONECUT high speed steel sheet & tube drill is a metal drill bit designed for rapid drilling and enlarging holes across a 6–20mm range. Ideal for installers and fabricators working with thin materials, it helps you achieve the hole size you need without swapping between multiple bit diameters.

Using the CC1 profile, the diameter increases as the tool advances, making it a practical choice for controlled hole opening in sheet and tube applications. The CC1 is compatible with drills accepting a 3/8in (10mm) chuck capacity.
