Walter-titex 5061923 Taper Length Drill Bit 0.2559 in

Product Description

The WALTER-TITEX 5061923 is a taper length twist drill bit designed for production drilling in metal fabrication and machining environments. Built from M-2 high speed steel with a coated finish, it measures 0.2559 inches (6.50 mm) in diameter and carries an overall length of 5.8281 inches (148.00 mm). The 130-degree split point with web thinning reduces thrust and improves centering without a pilot hole. A parabolic flute geometry with a 12xD flute-to-diameter ratio promotes efficient chip evacuation in deeper cuts. This bit is intended for use by machinists and tool-and-die trades working in general shop or CNC drill-press applications.

The 5061923 is rated for drilling aluminum, aluminum-silicon alloys, brass, bronze, copper alloys, stainless steel, and steel. Its parallel shank at 6.50 mm diameter fits standard drill chucks without adapters. The Series A1522 configuration follows DIN 340 standards, making it a recognized form factor in production shops. Typical applications include blind hole drilling, stack drilling, and through-hole drilling. Maximum drilling depth reaches 3.386 inches (86.00 mm), with a flute length of 3.8125 inches (97.00 mm) and a shank length of 2.008 inches (51.00 mm).

Key Features

• M-2 high speed steel construction with coated finish for extended tool life in ferrous and non-ferrous materials
• 130-degree point angle with UFL point type and web thinning for reduced entry thrust
• Parabolic flute geometry at 12xD ratio supports deep-hole chip clearance
• Parallel shank at 6.50 mm fits standard 3-jaw and collet-style drill chucks
• DIN 340 standard geometry for consistent interchangeability in production tooling setups
• Suitable for blind hole, stack drilling, and through-hole applications across multiple material types

Compatibility

Designed as a DIN 340 taper length drill bit for use in standard drill chucks accepting a 6.50 mm parallel shank, compatible with drilling aluminum, aluminum-silicon, brass, bronze, copper alloys, stainless steel, and steel workpieces.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals following applicable shop safety procedures. Ensure the drill press or CNC machine is fully powered down and locked out before mounting or removing the bit from the chuck. Secure the parallel shank firmly in a properly sized drill chuck or collet to the rated holding torque of the machine spindle. Do not exceed the rated maximum drilling depth of 3.386 inches without retracting to clear chips.
