Walter-titex 5236470 Screw Machine Drill Bit 8.4 Mm

Product Description

The WALTER-TITEX 5236470 is a screw machine length drill bit engineered for high-productivity drilling in demanding metalworking applications. Built from M35 cobalt high-speed steel, it delivers heat resistance and edge retention when cutting through tough materials. The 8.4 mm diameter bit features a 130-degree conical point with web thinning for improved centering and reduced thrust at entry. Overall length is 3.11 inches with a flute length of 1.46 inches and a maximum drilling depth of 0.94 inches. The parabolic flute geometry promotes efficient chip evacuation. This bit is designed to be installed and operated by machinists, tool-and-die technicians, and maintenance professionals working with ferrous and non-ferrous metals.

This drill bit is suited for production drilling in cast iron, non-ferrous metals, stainless steel, and general steel. The screw machine length format provides added rigidity compared to jobber-length bits, making it well suited for drill press, CNC machining center, and turret lathe applications where shorter flute length and reduced deflection are priorities. The straight-cylindrical shank accepts standard drill chucks and collet holders. Series A1149XPL is a universal performance offering conforming to DIN 1897 and ISO standards, covering the 8.00 to 9.50 mm diameter range grouping.

Key Features

• M35 cobalt construction for heat resistance and edge retention in hard metals
• 130-degree conical point with web thinning reduces thrust and improves self-centering
• Parabolic flute geometry promotes fast, reliable chip evacuation
• Screw machine length body provides greater rigidity and reduced deflection versus jobber bits
• Straight-cylindrical shank fits standard chucks and collet systems
• Meets DIN 1897 and ISO standards with h8 diameter tolerance

Compatibility

Designed for use in cast iron, non-ferrous metals, stainless steel, and steel workpieces. Compatible with standard drill chucks and collet holders accepting an 8.4 mm straight-cylindrical shank. Fits within the A1149XPL series covering the 8.00 to 9.50 mm diameter range per DIN 1897 specification.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tool safety. Secure the shank fully in a properly sized chuck or collet before operation and verify runout is within acceptable limits. Always follow machine guarding requirements and wear appropriate eye protection per applicable shop safety standards. Do not exceed the rated speed for the workpiece material and bit diameter.
