Walter-titex 5057170 Screw Machine Drill Bit 21/64 in

Product Description

The WALTER-TITEX 5057170 is a screw machine length drill bit engineered for high-performance drilling in demanding trade and industrial environments. Manufactured from Cobalt Vanadium High Speed Steel with a bright, uncoated finish, this bit features a parabolic flute geometry and a 130-degree split point that reduces walking and promotes clean entry. At 0.3281 inches (21/64 inch) in diameter with an overall length of 3-1/8 inches and a flute length of 1-7/16 inches, it is built for short-reach, high-precision applications where rigidity and chip evacuation matter. A web-thinned, tapered web configuration reduces thrust and improves hole quality across a wide range of workpiece materials.

This bit is suited for machining and fabrication environments where consistent, accurate holes are required in cast iron, stainless steel, carbon steel, hard materials, and non-ferrous metals. Its screw machine length profile makes it a practical choice for drill press work, CNC operations, and hand-held power tool use where reduced overhang and greater stability are priorities. The parabolic flute design promotes efficient chip removal at higher feed rates, making it effective in production drilling scenarios handled by machinists and metalworking professionals.

Key Features

• Cobalt Vanadium High Speed Steel construction for heat resistance and edge retention in hard materials
• 130-degree split point reduces center punch requirement and minimizes drill walking
• Parabolic flute geometry promotes rapid chip evacuation at aggressive feed rates
• Web-thinned, tapered web reduces drilling thrust and improves hole finish
• Right-hand cut with straight-cylindrical shank for compatibility with standard chucks
• Conforms to DIN, ISO, BS, and DIN specification standards for dimensional consistency

Compatibility

Designed for use in standard straight-shank drill chucks; suitable for drilling cast iron, hard materials, non-ferrous metals, stainless steel, and carbon steel as specified by the manufacturer for Series A1148.

Installation Notes

Installation of this drill bit should be performed by qualified machinists or metalworking tradespeople familiar with proper chuck mounting procedures. Ensure the drill press, CNC spindle, or power tool is fully powered down and secured before inserting or removing the bit. Use appropriate cutting fluid or coolant for the workpiece material when drilling stainless steel or hard alloys to extend tool life. Always verify chuck capacity and shank seating before beginning a drilling operation.
