Walter-titex 5154105 Taper Length Drill Bit 0.0420 in

Product Description

The WALTER-TITEX 5154105 is a taper length twist drill bit designed for precision drilling in a wide range of metallic materials. Built from high speed steel with a bright uncoated finish, it carries a 0.0420 inch diameter corresponding to wire gauge size 58. The 130-degree drill point angle and parabolic flute geometry promote efficient chip evacuation and reduce cutting forces, making this bit well suited for blind hole, through hole, and stack drilling operations. The web-thinned, tapered web configuration minimizes entry resistance. This bit is typically installed by machinists, tool-and-die technicians, and maintenance professionals working with precision drilling equipment.

The 5154105 is rated for use in aluminum, aluminum silicon, brass, bronze, copper alloy, stainless steel, and steel. Its 12xD flute length to diameter ratio and overall length of 2-3/8 inches give it added reach compared to a jobber-length bit, making it appropriate for applications requiring deeper hole penetration without switching to an extended series tool. The parallel shank fits standard drill chucks and collets without modification. Typical applications include production machining, maintenance repair, and fabrication environments where consistent hole quality in metalwork is required.

Key Features

• Wire gauge size 58 diameter at 0.0420 inches with a tight tolerance of -0.00055 to 0.00000 inches
• Parabolic flute design with web thinning for improved chip flow and reduced thrust force
• 130-degree standard point angle suitable for most ferrous and non-ferrous metals
• Taper length body at 2-3/8 inches overall with a 1-15/32 inch flute length
• Right-hand cut with parallel shank for compatibility with standard chucks and collets
• Conforms to DIN 340 standard; Series A1522 high performance grade

Compatibility

Designed for use in aluminum, aluminum silicon, brass, bronze, copper alloy, stainless steel, and steel workpieces. Suitable for blind hole, through hole, and stack drilling applications where a taper length geometry is specified.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or technician familiar with drilling feeds and speeds for the target material. Ensure the machine spindle and chuck are powered down and at a full stop before securing or removing the bit. Verify that the shank diameter seats fully and concentrically in the chuck or collet to prevent runout. Follow applicable shop safety standards and machine manufacturer guidelines for cutting fluid use and drill press or CNC operating parameters.
