Guhring 9002260170000 Screw Machine Drill Bit 17mm

Product Description

The GUHRING 9002260170000 is a screw machine length drill bit designed for left-hand cutting in metal fabrication and machining applications. Built from M2 high-speed steel with an oxide coating, this bit features a 118-degree cone relief point and a web-thinned tip geometry for reduced thrust and cleaner entry. At 17.00 mm in diameter with an overall length of 119.00 mm, the short screw machine length profile provides rigidity in turret lathes, screw machines, and drill presses where minimal overhang is critical. Machinists and tool-and-die professionals are the primary users. The 2-flute regular spiral design evacuates chips efficiently during through-hole and blind-hole drilling in ferrous materials.

This bit is suited for production machining environments where left-hand cutting direction is required — common when drilling out broken right-hand fasteners, reverse-threading operations, or on machines with left-hand spindle rotation. The straight cylindrical shank seats directly into standard chucks or collet systems without adapter hardware. The 3xD flute-to-diameter ratio and 60.00 mm flute length make it appropriate for moderate-depth holes in steel, cast iron, and similar general-purpose workpiece materials. Manufactured to DIN specification with an h8 diameter tolerance, it meets the dimensional standards expected in close-tolerance production work.

Key Features

• Left-hand cutting direction for reverse-spindle and broken-fastener applications
• M2 high-speed steel construction with oxide coating for lubricity and corrosion resistance
• 118-degree cone relief point with web thinning for reduced entry force
• Screw machine length body for maximum rigidity in turret and production setups
• h8 diameter tolerance to DIN specification for close-tolerance fitment
• 2-flute regular spiral geometry promotes consistent chip evacuation

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard straight-shank chucks and collet systems accepting a 17.00 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists familiar with cutting tool setup and spindle speed selection. Secure the shank fully in the chuck or collet and verify runout before production use. Confirm spindle rotation matches the left-hand cutting direction of this bit before engaging the workpiece. Cutting speed and feed rate should be selected based on workpiece material and machine rigidity; consult published HSS drilling parameters for the specific material grade being machined.
