Walter-titex 5236427 Screw Machine Drill Bit 4.30mm Cobalt

Product Description

The WALTER-TITEX 5236427 is a screw machine length cobalt drill bit designed for high-productivity drilling in demanding materials. Built to Series A1149XPL with an M35 cobalt steel construction, this bit features a 130-degree conical point with U-grind geometry and a parabolic flute profile for efficient chip evacuation. The 4.30 mm diameter and shortened overall length of 58 mm (2.2835 inches) make it well suited for stub-length drilling applications where rigidity and reduced deflection are priorities. Machinists, toolroom technicians, and production drilling operators are the primary users of this bit. It conforms to DIN 1897 and ISO standards, ensuring dimensional consistency across interchangeable tooling setups.

This bit is intended for drilling into cast iron, non-ferrous metals, stainless steel, and general steel workpieces. The screw machine length format is a standard choice on drill presses, CNC machining centers, lathes, and turret machines where a shorter, stiffer drill reduces runout and improves hole location accuracy. The parabolic flute geometry supports universal performance across these material groups, making the 5236427 a practical general-purpose option in production and maintenance machining environments. No coolant-through capability is present, so external flood or mist coolant application is recommended when drilling stainless steel or cast iron.

Key Features

• M35 cobalt construction provides heat resistance for drilling stainless steel and cast iron without premature edge breakdown
• 130-degree conical point with U-grind reduces thrust force and improves self-centering on hard materials
• Parabolic flute profile accelerates chip evacuation and reduces re-cutting in deep holes
• Web-thinned, tapered web configuration lowers cutting resistance at entry
• Straight-cylindrical shank at 4.30 mm diameter fits standard drill chucks and collets without adapters
• h8 diameter tolerance ensures consistent fit and repeatable hole sizing across production runs
• DIN 1897 and ISO compliance supports use in quality-controlled or documented manufacturing processes

Compatibility

Designed as an OEM-style screw machine length drill bit conforming to DIN 1897, suitable for use in any standard drill chuck or collet accepting a 4.30 mm straight-cylindrical shank. Applicable across the 3.50 mm to 5.00 mm drill bit size range category per supplier specification.

Installation Notes

Install the shank fully into the chuck or collet and verify runout before initiating a cut. Ensure the machine spindle is at a complete stop before changing or adjusting the bit. Use appropriate cutting fluid or mist coolant when drilling stainless steel or cast iron to extend tool life and maintain dimensional accuracy. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection based on workpiece material.
