Walter-titex 5236456 Screw Machine Drill Bit 7mm Cobalt

Product Description

The WALTER-TITEX 5236456 is a screw machine length cobalt drill bit designed for high-productivity drilling in demanding metalworking applications. Built to DIN 1897 and ISO standards, this bit features a 7 mm (0.2756 inch) diameter with a straight-cylindrical shank and a 130-degree conical point angle with U-point geometry. The parabolic flute design and web-thinned, tapered web configuration promote efficient chip evacuation and reduced thrust. At 74 mm (2.913 inches) overall length and an M35 cobalt material grade, this bit is built for consistent performance in production environments. Installed by machinists and tool-and-die professionals on drill presses, CNC machines, and hand-operated equipment.

The 5236456 is a universal-performance bit rated for use in cast iron, non-ferrous metals, stainless steel, and steel. The short screw machine length body reduces deflection and improves rigidity in close-tolerance work. With a maximum drilling depth of 22 mm (0.866 inches) and a flute-to-diameter ratio of 3xD, this bit suits repetitive production drilling where hole quality and tool life matter. Diameter tolerance is held to h8 per DIN specification, making it appropriate for precision fit applications.

Key Features

• 7 mm diameter with h8 tolerance per DIN 1897 and ISO standards
• M35 cobalt construction for heat resistance in ferrous and stainless steel applications
• 130-degree conical point with U-point geometry reduces walking and improves entry
• Parabolic flutes with web-thinned, tapered web for efficient chip removal
• Screw machine length body minimizes deflection in short-reach drilling setups
• Compatible with cast iron, non-ferrous metals, stainless steel, and steel

Compatibility

Designed for use in cast iron, non-ferrous metal, stainless steel, and steel workpieces. Part of the WALTER-TITEX A1149XPL series, covering the 6.50 mm to 8.00 mm diameter range.

Installation Notes

This drill bit is installed by machinists and metalworking technicians in drill presses, milling machines, and CNC equipment. Secure the shank fully in the chuck or collet before operation and verify spindle speed is appropriate for the workpiece material and bit diameter. Coolant-through capability is not supported on this bit; apply cutting fluid externally when drilling stainless steel or hardened alloys to extend tool life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
