Walter-titex 6968856 13mm Solid Carbide Screw Machine Drill Bit

Product Description

The WALTER-TITEX 6968856 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding shop and production environments. Measuring 13 mm (0.5118 inches) in diameter with an overall length of 107 mm (4.213 inches), this bit features a 140-degree split point and a TiNAl coating for extended tool life. The two-flute, right-hand cut design delivers efficient chip evacuation, while the coolant-through construction allows internal coolant delivery directly to the cutting zone. Licensed machinists and tool-room technicians are the primary installers and operators of this bit.

This drill bit is rated for universal tool performance across multiple workpiece materials including cast iron, hard materials, non-ferrous metals, and steel. Its screw machine length profile makes it well suited for CNC machining centers, drill presses, and manual mills where stub-length rigidity and reduced deflection are required. The straight-cylindrical shank measures 14 mm (0.551 inches) in diameter and 45 mm (1.770 inches) in length, providing consistent chuck retention. The 3xD flute-to-diameter ratio supports controlled chip removal in through-hole and blind-hole applications.

Key Features

• Solid carbide construction for high rigidity and wear resistance in hard and abrasive materials
• TiNAl coating extends cutting life and reduces heat buildup at the cutting edge
• 140-degree point angle reduces entry thrust and improves self-centering on flat or curved surfaces
• Coolant-through design delivers coolant directly to the cutting zone for deep-hole applications
• Straight-cylindrical shank compatible with standard ER collets and drill chucks
• Meets DIN and ISO standards; diameter tolerance class m7 for predictable hole sizing

Compatibility

Part of the WALTER-TITEX DC150-03-A1 series. Suitable for drilling cast iron, hard materials, non-ferrous metals, and steel. Fits applications requiring a drill bit in the 11.00 mm to 13.50 mm size range (0.5000 to 0.6000 decimal inch).

Installation Notes

Installation and operation should be performed by qualified machinists following applicable shop safety procedures. Ensure the machine spindle is fully stopped and locked out before changing or seating the bit in the collet or chuck. Verify coolant-through lines are properly connected and flow is confirmed before initiating deep-hole cycles. Do not exceed the maximum drilling depth of 43 mm (1.693 inches) per the tool specification.
