Cleveland C00980 Screw Machine Drill Bit Set 29 Pc Hss

Product Description

The CLEVELAND C00980 is a 29-piece screw machine length drill bit set designed for high-volume metalworking and multipurpose drilling applications. Each bit is manufactured from high-speed steel (HSS) with a bright, uncoated finish and a standard 118-degree split-free point for accurate starting without a center punch in most materials. The straight shank design is compatible with standard drill chucks. This set covers fractional inch sizes from 1/16 inch to 1/2 inch in 1/64-inch step increments, making it a practical all-in-one solution for shops and field technicians who need a consistent size range on hand.

Screw machine length drill bits have a shorter overall length than jobber-length bits, which provides increased rigidity and reduced deflection during drilling. This makes the C00980 set well suited for use in drill presses, lathes, and CNC equipment, as well as portable drill applications where chatter and bit wander are concerns. Typical users include machinists, HVAC technicians drilling sheet metal and structural members, plumbers drilling through framing and mechanical supports, and electricians working with metal electrical enclosures and strut. The included metal or plastic case keeps all 29 bits organized and protected between uses.

Key Features

• 29-piece fractional set covers 1/16 inch to 1/2 inch in 1/64-inch increments

Compatibility

Designed as a general-purpose fractional drill bit set for use with standard three-jaw drill chucks on portable drills, drill presses, lathes, and CNC equipment in metalworking and multipurpose trade applications.

Installation Notes

Install bits securely in a properly sized chuck and verify the chuck key is removed before powering the tool. Wear eye protection and secure the workpiece before drilling. For metalworking applications, apply a cutting fluid to extend bit life and improve hole quality, particularly at larger diameters. Inspect each bit for wear or damage before use and replace any bit showing cracks, chipped flutes, or excessive dulling.
