Walter-titex 5057074 Screw Machine Drill Bit 0.12 in

Product Description

The WALTER-TITEX 5057074 is a screw machine length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built from Cobalt Vanadium High Speed Steel with a bright, uncoated finish, it measures 0.12 inches in diameter and runs an overall length of 1-15/16 inches. The split point tip at a 130-degree angle starts on contact without walking, reducing the need for a center punch. A parabolic flute geometry promotes efficient chip evacuation and allows deeper penetration per pass. This bit is suited for machinists, maintenance technicians, and fabricators working with tight-tolerance hole requirements in production or field environments.

The 5057074 is built for drilling cast iron, stainless steel, hardened materials, non-ferrous metals, and general steel stock. Its screw machine length profile - shorter than a jobber bit - provides added rigidity and reduced deflection, making it well-suited for drill press work, CNC setups, and hand drilling in confined spaces. The 3xD flute-to-diameter ratio and tapered web configuration support consistent performance across a range of material hardnesses. It carries DIN, ISO, BS, and DIN specification designations, confirming dimensional conformance to recognized international standards.

Key Features

• Cobalt Vanadium High Speed Steel construction for heat resistance and edge retention in hard materials
• 130-degree split point tip reduces thrust and eliminates center-punch requirement
• Parabolic flute design improves chip flow and reduces heat buildup during drilling
• Screw machine length body increases rigidity and minimizes deflection versus jobber-length bits
• Right-hand cut with straight cylindrical shank for compatibility with standard drill chucks and collets
• Web-thinned tapered web for reduced cutting resistance and improved penetration rate

Compatibility

Designed for use in standard straight-shank drill chucks and collets accepting a 0.12-inch diameter shank. Rated for primary workpiece materials including cast iron, hard material, non-ferrous metal, stainless steel, and steel. Conforms to Series A1148 specifications per DIN, ISO, and BS standards.

Installation Notes

Installation and use of this drill bit should follow standard machining safety practices. Secure the workpiece firmly before drilling and ensure the chuck is properly tightened to the straight cylindrical shank before operation. Verify spindle speed is appropriate for the workpiece material and bit diameter per published cutting speed tables. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed to maintain hole tolerance and prevent tool breakage.
