15-piece reduced-shank drill set

The Cle-Line C21156 set contains fifteen high-speed steel jobber bits with a 3/8 reduced shank and 118-degree point angle. A black oxide finish adds corrosion resistance during general-purpose drilling. The range suits workshop technicians and maintenance crews who need a broad selection in one case.

Check your chuck capacity and material

Verify that your drill chuck accepts a 3/8 shank diameter before ordering. The 118-degree point is intended for general-purpose metal and wood drilling rather than specialised alloys or hardened steel. Ensure the workpiece material matches the high-speed steel capability.

Sustained drilling with black oxide finish

Under continuous use the high-speed steel body resists heat buildup while the black oxide surface helps retain cutting fluid. The reduced shank design maintains rigidity across the full bit length during extended drilling cycles. Performance stays consistent across the fifteen-piece range.
