Walter-titex 5337147 7/16 Inch Cobalt Screw Machine Drill Bit

Product Description

The WALTER-TITEX 5337147 is a cobalt screw machine length drill bit ground to a 130-degree conical point with web thinning for reduced thrust and cleaner entry. Built from M35-grade cobalt steel, it measures 3.74 inches overall with a 7/16-inch (0.4375-inch) straight-cylindrical shank and a parabolic flute geometry that improves chip evacuation in deep-hole applications. The h8 diameter tolerance on the shank ensures consistent fit in standard drill chucks and collet holders. This bit is intended for installation and maintenance professionals working with ferrous and hard materials who need a short, rigid drill for confined-space or machine-spindle work.

The 5337147 is suited for drilling cast iron, stainless steel, carbon steel, and non-ferrous metals in both production and field environments. The screw machine length body provides rigidity and reduced deflection compared to jobber-length bits, making it a practical choice for CNC drilling, drill press operations, and tight-clearance hand-drill applications. The parabolic flute profile with tapered web configuration supports efficient chip removal at standard to moderate feed rates across the primary workpiece materials listed.

Key Features

• M35-grade cobalt steel construction for heat resistance when drilling hardened and stainless materials
• 130-degree conical point with web thinning reduces entry thrust and improves hole accuracy
• Parabolic flute geometry with tapered web promotes chip flow and reduces clogging
• Screw machine length body (3.74 inches OAL) provides increased rigidity over jobber-length alternatives
• Straight-cylindrical shank at h8 tolerance fits standard drill chucks and collet systems
• Conforms to DIN 1897 and ISO dimensional standards

Compatibility

Designed as a screw machine length drill bit for use in drill presses, CNC machining centers, and hand drills accepting a 7/16-inch straight-cylindrical shank. Primary workpiece materials include cast iron, non-ferrous metal, stainless steel, and steel per the manufacturer specification for Series A1149XPL.

Installation Notes

Machining professionals and maintenance technicians should secure the shank fully in the chuck or collet before operation and verify runout before drilling hardened or stainless workpieces. Always power down and lock out the machine spindle before changing bits. Use cutting fluid or coolant appropriate for the workpiece material when drilling stainless steel or cast iron to extend tool life. Note that this bit is not configured for coolant-through delivery.
