Guhring 9005490034500 Jobber Drill No 29 Hss 130 Deg

Product Description

The GUHRING 9005490034500 is a No. 29 wire-size jobber-length drill bit engineered for demanding metal-cutting applications. Built from high speed steel (HSS) with a bright/uncoated finish, it features a 130-degree split point and a parabolic flute profile that promotes faster chip evacuation and reduced feed force. The overall length is 2.75 inches with a flute length of 1.5313 inches, keeping the drill compact and stiff for accurate hole location. Right-hand cutting geometry and a web-thinned, tapered-web design reduce the thrust required at entry. This bit is suited for professionals who drill steel, cast iron, and aluminum in production or field settings.

This jobber drill is intended for use in light to heavy-duty drilling of steel, cast iron, aluminum, and other non-ferrous materials. Its 5xD flute-to-diameter ratio and parabolic flute form make it a practical choice for through-hole work on structural components, machine frames, and sheet metal. The straight cylindrical shank fits standard drill chucks on hand drills, drill presses, and CNC spindles without adapters. It conforms to DIN 338 standards and falls within the heavy-duty drill bit grade, making it appropriate for industrial shop environments as well as trade fieldwork.

Key Features

• No. 29 wire size with a 0.1360-inch decimal diameter for precise undersized hole work
• 130-degree point angle with web thinning reduces entry thrust and walking tendency
• Parabolic flute geometry accelerates chip clearance in deep holes
• High speed steel construction handles intermittent cuts in ferrous and non-ferrous materials
• Conforms to DIN 338 specification for consistent dimensional tolerances
• Bright/uncoated finish allows visual wear monitoring during service

Compatibility

Designed as a DIN 338-compliant jobber drill for use in standard straight-shank drill chucks across hand drills, drill presses, and CNC machining centers. Suitable for primary workpiece materials including steel, cast iron, aluminum, and non-ferrous metals as specified by the manufacturer.

Installation Notes

Installation is performed by machinists, tool-and-die tradespeople, or experienced maintenance mechanics. Secure the straight shank fully in the chuck and verify runout before drilling. Power down the machine and lock out energy sources before changing bits or clearing chips. Do not exceed the recommended maximum drilling depth of 1.332 inches in a single pass without retracting to clear chips.
