Walter-titex 5057252 Screw Machine Drill Bit 0.378 in

Product Description

The WALTER-TITEX 5057252 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, this bit delivers heat resistance and edge retention when cutting through hard and abrasive materials. The 130-degree split point and parabolic flute geometry reduce walking on entry and clear chips efficiently. At 0.378 inches in diameter with a 3.5-inch overall length and a 1-11/16-inch flute length, this bit fits compact drilling envelopes where a jobber-length bit is too long. A straight-cylindrical shank seats cleanly in standard chucks. It carries a bright, uncoated finish and is web-thinned with a tapered web configuration for reduced thrust requirements.

This drill bit is suited for machinists, tool and die shops, fabrication operations, and maintenance technicians working with cast iron, stainless steel, carbon steel, hard materials, and non-ferrous metals. The screw machine length format is standard in turret lathes, CNC machining centers, and drill presses where short, rigid tooling is required for close-tolerance work. The A1148 series is classified as universal performance, making it a practical choice for shops that run mixed-material production without swapping specialty tooling. Minimum order quantity is 10 pieces; package quantity is 1.

Key Features

• Cobalt Vanadium High Speed Steel construction for heat and wear resistance in hard and abrasive materials
• 130-degree split point reduces drill walking and lowers thrust at entry
• Parabolic flute profile promotes fast chip evacuation and reduces recutting
• Web-thinned tapered web lowers cutting resistance and extends tool life
• Screw machine (stub) length provides rigidity for tight-clearance and CNC setups
• Meets DIN, ISO, and BS standards for dimensional and performance consistency

Compatibility

Designed for use in cast iron, hard materials, non-ferrous metals, stainless steel, and carbon steel. Compatible with standard drill chucks and collets accepting a straight-cylindrical shank at 0.378 inches diameter. Conforms to DIN, ISO, and BS specifications under Series A1148.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Secure the shank fully in a properly rated chuck or collet before operation and verify spindle speed is appropriate for the workpiece material and bit diameter. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Do not exceed the maximum drilling depth of 1.1 inches without retracting to clear chips.
