Walter-titex 7378139 Screw Machine Drill Bit 0.2362 in Carbide

Product Description

The WALTER-TITEX 7378139 is a solid carbide screw machine length drill bit designed for high-precision hole-making in demanding industrial and trade applications. Built to Series DC160-03-A1 standards, it features a 0.2362-inch diameter, a 140-degree split-point tip, and a straight-cylindrical shank for secure chuck seating. The two-flute geometry and coolant-through design allow effective chip evacuation and thermal management during deep drilling cycles. At 2.598 inches overall length and a flute length of 1.102 inches, this bit is sized for screw machine and CNC drilling operations where rigidity and repeat accuracy are critical. Licensed machinists, tool-and-die technicians, and precision metalworking shops are the primary users of this bit.

This drill bit is rated for use in cast iron, hard materials, non-ferrous metals, and steel, making it a versatile choice across production machining environments. The Universal Advance tool performance rating and m7 diameter tolerance classification indicate suitability for tight-tolerance bore work. A maximum drilling depth of 0.787 inches and a 3xD flute-to-diameter ratio define its operational range. It conforms to DIN and ISO standards, supporting use in both domestic and international manufacturing workflows. Packaged as a single unit, it fits standard screw machine drill setups and CNC machining centers running the DC160-03-A1 series.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• 140-degree drill point angle for self-centering entry and reduced thrust force
• Coolant-through design directs cutting fluid directly to the drill tip for thermal control and chip flushing
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• m7 diameter tolerance provides consistent bore sizing for precision fit applications
• Conforms to DIN and ISO standards for interchangeability in regulated manufacturing environments

Compatibility

Designed for use in screw machine drill setups and CNC machining centers that accept straight-cylindrical shank bits in the 0.2000-inch to 0.2500-inch diameter range, Series DC160-03-A1. Suitable for workpieces in cast iron, hard materials, non-ferrous metals, and steel.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the shank fully into the collet or drill chuck before initiating any spindle operation. Ensure coolant lines are connected and flowing before engaging the drill in coolant-through mode to prevent tip overheating. Follow machine manufacturer torque and runout specifications for tool holding; do not exceed the rated maximum drilling depth of 0.787 inches per pass without confirming chip clearance.
