Guhring 9005490051600 Jobber Drill Bit 13/64 in Hss

Product Description

The GUHRING 9005490051600 is a jobber length drill bit designed for precision drilling in a range of materials. Built from high speed steel with a bright, uncoated finish, it measures 13/64 inches (0.2031 inches decimal) in diameter with a 3-3/8 inch overall length. The 130-degree split point reduces walking on entry, and the parabolic flute geometry improves chip evacuation and cutting efficiency. This is a Series 549 bit conforming to DIN 338 standards, offered as a high performance grade for demanding production and field applications. Licensed trades and machining professionals use this bit where consistent hole quality and tool life matter.

This drill bit is optimized for use on aluminum and non-ferrous metals, as indicated by its primary workpiece material ratings (material codes K, N, and P). It is suited for residential and light commercial fabrication, HVAC sheet metal work, electrical panel and conduit layout, plumbing rough-in, and general mechanical assembly. The straight-cylindrical shank fits standard drill chucks without adapters. The 5xD flute-to-diameter ratio and web-thinned, tapered web construction make it particularly effective in softer materials where clean entry and chip clearance are priorities.

Key Features

• 13/64 inch diameter (0.2031 inches decimal) with tight tolerance of -0.018 to 0.000 mm
• Parabolic flute design promotes aggressive chip evacuation in aluminum and similar materials
• 130-degree drill point angle with web thinning reduces thrust and minimizes bit walking
• High speed steel construction rated as high performance grade per DIN 338
• 2-flute, right-hand cut with straight-cylindrical shank for universal chuck compatibility
• Bright/uncoated finish suitable for use without coolant (coolant-through: No)

Compatibility

Designed as a DIN 338 Series 549 jobber length drill bit suited for aluminum, non-ferrous metals, and plastics (material codes K, N, P). Compatible with any standard drill chuck accepting a 13/64 inch straight-cylindrical shank.

Installation Notes

Install in a drill press, hand drill, or CNC spindle with a chuck rated for the shank diameter. Secure the shank fully in the chuck before operation and confirm runout is within acceptable limits for the application. Power down and de-energize all equipment before changing bits. Follow applicable shop safety standards and, for field work, NEC or trade-specific codes governing drilling near electrical conductors or structural members.
