118-Degree Point Angle Drill Bit

The Cle-Line C20758 is a Silver & Deming drill bit designed for general-purpose drilling tasks. It features a 118-degree point angle suitable for a range of materials. The reduced shank allows compatibility with standard 1/2-inch chucks. This accessory targets professionals and DIY users needing reliable hole-making capability.

Upgrade from Standard Twist Bits

This bit replaces smaller twist drills when hole diameters exceed chuck capacity limits. The 1/2-inch reduced shank bridges the gap for larger holes without requiring a larger drill press. The jump is worth it when your current bits cannot fit the required shank size. Machining High Speed Steel construction supports durability in steel and cast iron.

Sustained Load Behaviour

Black Oxide finish helps retain lubricant and reduces chip welding during extended cutting. The 118-degree geometry maintains centring accuracy over repeated holes. Machining High Speed Steel resists heat buildup better than carbon steel alternatives. Consistent feed pressure yields straight holes without walking in tough alloys.

Questions about this item

What chuck size is required for the 1/2 reduced shank on the C20758 drill bit?

The 1/2 reduced shank fits any standard 1/2 inch drill chuck, allowing use with smaller capacity drills.

How should the 118 degree point angle be aligned when starting a hole in steel?

Centre-punch the mark, apply steady pressure, and keep the bit perpendicular so the 118 degree point centres itself without walking.

When does the black oxide finish on this high speed steel bit need to be refreshed?

Reapply a light oil coating when the black oxide shows wear or rust to maintain lubricity and corrosion resistance.
