Walter-titex 5200207 Screw Machine Drill Bit 1/4 in Carbide

Product Description

The WALTER-TITEX 5200207 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial applications. It features a 1/4 inch (0.2500 inch decimal) cutting diameter, a 150-degree standard point angle, and a web-thinned, parallel web construction that reduces thrust and improves chip evacuation. At 91 millimeters overall length with a spiral flute and right-hand cutting direction, this bit is built for short-reach, high-rigidity setups. Coolant-through capability supports extended tool life at elevated feeds and speeds. Licensed HVAC techs, machinists, and maintenance professionals working with hard or abrasive materials will find this bit suited for production drilling cycles.

This drill bit is intended for use on cast iron, hard materials, non-ferrous metals, stainless steel, and steel workpieces. Its screw machine length body provides the rigidity needed for CNC machining centers, drill presses, and turret lathes where stub-length tooling is preferred. The A6181TFT series designation identifies this as a universal-performance tool conforming to DIN and ISO standards, making it appropriate for job shops and production environments that require consistent, repeatable hole quality across mixed material schedules.

Key Features

• Solid carbide construction in material grade K30F for hardness and wear resistance in ferrous and non-ferrous materials
• 150-degree point angle with standard point type reduces walking and improves entry on flat and curved surfaces
• Coolant-through design channels cutting fluid directly to the cutting edge for heat management and chip flushing
• Web-thinned parallel web lowers axial thrust and supports higher feed rates
• Straight-cylindrical shank at 8.00 millimeters (0.3150 inch decimal) fits standard collet chucks and drill chucks
• Conforms to DIN 6535HA specification and meets DIN and ISO standards for dimensional consistency

Compatibility

Designed for use in CNC machining centers, drill presses, and turret lathes accepting a straight-cylindrical shank. Primary workpiece materials include cast iron, hard materials, non-ferrous metals, stainless steel, and steel. Drill bit size range for this series is 0.2500 to 0.3000 decimal inch.

Installation Notes

Installation and tool changes should be performed by qualified machinists or tool-room personnel with the machine powered down and locked out per OSHA lockout/tagout procedures. Seat the straight-cylindrical shank fully in the collet or chuck and verify runout before initiating a cut. Coolant-through tooling requires a machine spindle configured to deliver coolant internally — confirm spindle compatibility before mounting. Do not exceed the manufacturer-rated maximum drilling depth of 0.9060 inch (23.00 millimeters) per pass without retracting to clear chips.
