Walter-titex 5057205 Screw Machine Drill Bit 0.2165 in

Product Description

The WALTER-TITEX 5057205 is a screw machine length drill bit designed for high-performance drilling across a wide range of metalworking applications. Manufactured from cobalt vanadium high speed steel, it delivers the hardness and heat resistance needed for demanding materials including stainless steel, cast iron, and hard alloys. The bit measures 0.2165 inches in diameter with an overall length of 2-19/32 inches and features a 130-degree split point for accurate entry without center-punching. A parabolic flute geometry promotes fast chip evacuation and reduces heat buildup during extended drilling cycles. This bit is intended for installation and production shops where repeated precision drilling is required.

The 5057205 is suited for drilling stainless steel, cast iron, hard materials, non-ferrous metals, and general steel in both production and maintenance environments. Its screw machine length profile fits most standard drill chucks and CNC machine tooling setups. The parabolic flute and web-thinned, tapered web configuration support efficient chip flow at the higher feed rates these materials often demand. The 3xD flute-to-diameter ratio supports a maximum drilling depth of 0.7000 inches, keeping it practical for typical through-hole and blind-hole work in plate and structural stock.

Key Features

• Cobalt vanadium high speed steel construction for heat and wear resistance in tough materials
• 130-degree split point reduces thrust and improves hole entry accuracy
• Parabolic flute design accelerates chip evacuation and reduces clogging
• Web-thinned, tapered web lowers cutting forces for cleaner hole finishes
• Straight-cylindrical shank fits standard drill chucks without adapters
• Meets DIN, ISO, and BS dimensional and performance standards

Compatibility

Designed as a universal-grade screw machine length drill bit compatible with standard drill press, lathe, and CNC machining center spindles accepting straight-cylindrical shanks. Rated for primary workpiece materials including cast iron, hard materials, non-ferrous metals, stainless steel, and steel per the manufacturer Series A1148 specification.

Installation Notes

Installation and operation should be performed by a qualified machinist or tooling technician familiar with cutting tool setup and machine safety procedures. Secure the shank firmly in a properly sized drill chuck or collet before operation and verify runout is within acceptable tolerance. Always power down and de-energize the machine before changing tooling. Do not exceed the recommended maximum drilling depth of 0.7000 inches for this bit geometry.
