Titan Usa MS99431 Jobber Drill Bit Set 29 Pc Hss

Product Description

The TITAN USA MS99431 is a 29-piece jobber length drill bit set covering fractional inch sizes from 1/16 inch through 1/2 inch in standard 1/64-inch increments. Each bit is machined from high-speed steel with a black oxide and gold finish for lubricity and corrosion resistance. The 135-degree split-point tip reduces walking on contact, eliminating the need for a center punch in most applications. Straight shanks are compatible with standard keyless and keyed chucks. All 29 bits store in an included plastic index case. This set is suited for electricians, plumbers, HVAC technicians, and general mechanical contractors who need a full fractional range on the job.

This drill bit set is designed for drilling through ferrous and non-ferrous metals, wood, plastics, and composite materials encountered in residential and light commercial trade work. It covers every fractional size from 1/16 inch to 1/2 inch, making it a practical single-case solution for field service vehicles, shop benches, and installation crews. The jobber length geometry provides the reach and chip clearance needed for typical through-hole work in conduit, pipe flange, sheet metal, and structural members.

Installation Notes

Drill bit sets of this type are installed and used by licensed electricians, plumbers, HVAC technicians, and general contractors. Always secure the workpiece before drilling and wear appropriate eye protection. Match drill speed to material hardness — lower RPM for harder metals, higher RPM for softer materials and plastics. Inspect each bit for chipping or dulling before use and replace worn bits to avoid workpiece damage or bit breakage.
