Walter-titex 6618086 Screw Machine Drill Bit 13/64 in

Product Description

The WALTER-TITEX 6618086 is a solid carbide screw machine length drill bit designed for high-precision drilling in steel and cast iron. The 13/64-inch (0.2030 inch) diameter bit features a 140-degree split point and a TiNAl coating that extends tool life in ferrous materials. At 3 inches overall length, this is a stub-length format built for rigidity and accuracy in short-hole applications. The straight cylindrical shank and right-hand spiral flute make it compatible with standard drill chucks and toolholders. It is sold individually and suited for CNC machining centers, drill presses, and production environments where consistent hole quality is required.

This bit is intended for screw machine length applications in metalworking and machining operations. Its universal tool performance rating and Series DC150-03-A0 designation place it in a professional-grade category for shops drilling steel and cast iron on a regular basis. With a flute length of 39/64 inch (0.6090 inch) and a maximum drilling depth of 0.6090 inch, it is optimized for shallow, accurate bores rather than deep-hole work. Machinists, tool-and-die technicians, and CNC operators working in production environments are the primary installers and users.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• TiNAl coating extends tool life when drilling steel and cast iron
• 140-degree point angle reduces thrust and improves centering without a pilot hole
• Screw machine (stub) length format maximizes rigidity and minimizes deflection
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Meets DIN and ISO standards with m7 diameter tolerance for consistent fit

Compatibility

Designed for use in steel and cast iron workpieces. Fits standard straight-shank drill chucks and collet holders accepting a 0.2360-inch shank diameter. Series DC150-03-A0, covering drill bit sizes in the 0.2000- to 0.2500-inch decimal inch range (5.00 to 6.50 mm).

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with CNC or manual drilling equipment. Ensure the machine spindle is fully stopped and the toolholder is secure before inserting or removing the bit. Verify that spindle speed and feed rate are set per the workpiece material requirements before beginning a cut. Do not use this bit in hand-held power drills; it is intended for rigid machine tool setups only.
