Walter-titex 5057084 Screw Machine Drill Bit 0.098 in

Product Description

The WALTER-TITEX 5057084 is a screw machine length drill bit designed for high-performance drilling in demanding materials. Built from cobalt and vanadium high speed steel with a bright, uncoated finish, this bit delivers the edge retention and heat resistance required when working cast iron, stainless steel, hard materials, and non-ferrous metals. The parabolic flute geometry promotes efficient chip evacuation, reducing heat buildup during deep passes. A split point tip with web thinning reduces thrust on entry and helps the bit self-center without a pilot hole. Rated for universal tool performance under the Series A1148 classification, this bit meets DIN and ISO standards. Licensed tradespeople and machining professionals select this style for production drilling and precision fit work.

This drill bit is suited for screw machine length applications in both shop and field environments where a compact, rigid bit is preferred over a jobber length. The 0.098 inch diameter corresponds to Wire Size 40, making it a standard choice for tap-drill operations, pilot holes, and through-hole work in steel, cast iron, stainless, and non-ferrous stock. Its straight-cylindrical shank seats reliably in standard three-jaw drill chucks and collet-style tool holders across a wide range of machines.

Key Features

• Cobalt and vanadium high speed steel construction for improved heat and wear resistance in hard materials
• Parabolic flute design promotes fast chip evacuation and reduces heat in the cut zone
• Split point with web thinning lowers entry thrust and improves self-centering accuracy
• Tapered web configuration maintains rigidity along the full flute length
• Bright, uncoated finish compatible with a wide range of cutting fluids and dry cutting setups
• Conforms to DIN, ISO, and BS standards for dimensional accuracy and grade classification

Compatibility

Designed as a screw machine length drill bit for use in standard drill chucks and collet holders; compatible with cast iron, hard materials, non-ferrous metals, stainless steel, and general steel workpieces as stated by the manufacturer.

Installation Notes

This bit is installed by machinists and maintenance technicians in drill presses, CNC machining centers, and handheld power tools with appropriate chuck capacity. Secure the straight-cylindrical shank firmly in the chuck before operation and verify runout is within acceptable limits. Use a cutting fluid appropriate for the workpiece material to prolong edge life, particularly when drilling stainless steel or hardened stock. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised.
