Guhring 9005150093400 Drill Bit 0.3677 in Powdered Metal

Product Description

The GUHRING 9005150093400 is a stub-length, parabolic-flute drill bit engineered for high-performance drilling in cast iron and steel. Built to DIN 1897 specifications, this screw machine length bit features a powdered metal construction with a coated finish for extended tool life in production environments. The 130-degree point angle and cone relief point geometry reduce thrust and improve chip evacuation, while the web-thinned design makes entry into hard ferrous materials more efficient. With an overall length of 3.3071 inches and a flute length of 1.5748 inches, this bit is sized for compact, rigid setups common in machining and fabrication shops.

This drill bit is intended for use in CNC machining centers, drill presses, and screw machine applications where shorter tool overhang and higher feed rates are required. It is well suited for production drilling in cast iron and steel workpieces where chip control and hole accuracy are critical. The parabolic flute profile moves chips out of the cut zone quickly, reducing heat buildup and tool wear during repeated-cycle operations. Machinists and tool and die professionals will find this bit appropriate for tight-tolerance, high-volume hole-making tasks.

Key Features

• Powdered metal construction with coated finish for increased wear resistance
• 130-degree point angle with cone relief for reduced thrust in ferrous materials
• Parabolic fast-spiral flute design promotes rapid chip evacuation
• Web-thinned point for easier penetration and improved centering
• Straight-cylindrical shank fits standard drill chucks and collets
• Built to DIN 1897 standard; diameter tolerance h8 for consistent fitment

Compatibility

Designed as a DIN 1897 stub-length replacement drill bit for use in standard straight-shank drill chucks and collets. Primary workpiece materials are cast iron and steel. Fits within the 0.3500 to 0.4000 inch drill bit size range.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with rotary cutting tool safety. Ensure the machine spindle and workpiece are fully secured before beginning any drilling operation. Confirm chuck or collet runout is within acceptable tolerance to preserve the h8 diameter tolerance of the bit. Do not exceed the maximum recommended drilling depth of 1.0230 inches for this stub-length configuration.
