The PRECISION TWIST DRILL 5995681 is a 115-piece jobber length drill bit set covering wire gauge sizes 60 through 1, letter sizes A through Z, and fractional inch sizes from 1/16 inch to 1/2 inch. Built from high speed steel with a bright, uncoated finish, each bit features a standard 118-degree point angle and a straight shank. This comprehensive set is sized for general-purpose metalworking and multipurpose drilling tasks. HVAC technicians, plumbers, electricians, and maintenance trades rely on full-range sets like this for field work and shop use where varied hole sizes are a daily requirement.

This set is well suited to residential and light commercial trade applications where drilling into steel brackets, electrical enclosures, pipe hangers, sheet metal, and structural framing is routine.

Installation Notes

Drill bit sets of this type are used by licensed tradespeople including electricians, HVAC technicians, and plumbers for field drilling into metal substrates. Ensure the drill or drill press is powered off and unplugged before changing bits. Secure the workpiece before drilling and use appropriate cutting fluid when drilling hardened or thick steel to reduce heat buildup and extend bit life. Follow applicable safety standards and PPE requirements for drilling operations.
