Walter-titex 5337173 Screw Machine Drill Bit No. 30

Product Description

The WALTER-TITEX 5337173 is a cobalt screw machine length drill bit in wire gauge size No. 30 (0.1285 inches), designed for high-performance drilling in demanding shop and production environments. It features a 130-degree conical point with web thinning for accurate self-centering and reduced thrust on entry. The parabolic flute geometry promotes efficient chip evacuation, making this bit well suited for interrupted cuts and deep-hole applications relative to its short overall length of 1.929 inches (49 mm). Machinist and tool-and-die professionals are the primary users of this style of bit.

This drill bit is rated for use in cast iron, non-ferrous metals, stainless steel, and general steel stock. The screw machine length format - shorter than jobber length - delivers added rigidity and improved hole straightness in CNC machining centers, drill presses, and manual machines where stub-length tooling is preferred. The straight-cylindrical shank with a diameter of 0.1283 inches fits standard drill chucks without the need for an adapter. Series A1149XPL bits conform to DIN 1897 specification.

Key Features

• Wire gauge size No. 30 with a decimal diameter of 0.1285 inches for precise hole sizing
• M35 cobalt material grade provides heat and wear resistance when cutting hard and abrasive materials
• 130-degree conical point with web thinning reduces walking and entry thrust
• Parabolic 2-flute geometry aids chip clearance in deep and interrupted cuts
• Screw machine (stub) length at 1.929 inches overall adds rigidity over standard jobber bits
• Straight-cylindrical shank; right-hand cut; DIN and ISO compliant; h8 diameter tolerance

Compatibility

Designed as an OEM-style replacement or direct substitute for screw machine length drill bits conforming to DIN 1897 in wire gauge No. 30. Suitable for use in standard drill chucks accepting a 0.1283-inch straight-cylindrical shank across CNC and manual drilling equipment.

Installation Notes

Installation of this bit is performed by machinists or tool-room technicians. Secure the straight-cylindrical shank fully into the drill chuck and verify concentricity before operation. Power down and lock out the machine before changing tooling. Follow the machine manufacturer spindle speed and feed recommendations for the workpiece material being drilled; no specific values are provided here.
