Value Collection 01290857 Screw Machine Drill Bit 1.70mm Hss

Product Description

The VALUE COLLECTION 01290857 is a screw machine length drill bit designed for close-tolerance drilling in metal, plastic, and general-purpose materials. At 1.70 mm in diameter with a 118-degree standard point angle, this bit is suited for applications requiring a short, rigid cutting tool with reduced deflection. The high-speed steel (HSS) construction with an oxide finish provides basic corrosion resistance and heat dissipation during cutting. The straight cylindrical shank fits standard drill chucks, and the right-hand spiral flute geometry evacuates chips efficiently during through-hole and blind-hole operations. Machinists, tool-and-die technicians, and maintenance trades use this bit in drill presses, CNC machines, and hand drills.

This bit is a general-purpose screw machine length drill intended for production and maintenance drilling where a shorter overall length improves rigidity and accuracy. The 1.70 mm diameter falls within the 0.00 to 3.50 mm size range, making it appropriate for fine-pitch pilot holes, tap drilling, and precision hole work in light metals and plastics. The web-thinned, parallel-web design reduces thrust force at the cutting tip, making it practical for harder materials or where feed pressure must be controlled.

Key Features

• 1.70 mm (0.0669 inch) diameter for fine-pitch and small-hole drilling applications
• 118-degree standard point angle for general-purpose material compatibility
• High-speed steel construction provides durability across metal and plastic substrates
• Oxide coating offers basic heat and corrosion resistance at the cutting zone
• Web-thinned parallel web reduces cutting thrust and extends bit life
• Screw machine length body increases rigidity and reduces deflection versus jobber-length bits

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard straight-shank drill chucks on drill presses, CNC drilling stations, and hand-held power drills accepting small-diameter bits.

Installation Notes

This bit is installed and serviced by machinists, maintenance technicians, and trade professionals using standard drill chuck equipment. Secure the straight shank fully in the chuck jaws before operation and verify runout is within acceptable tolerance for the application. Use appropriate cutting fluid or lubricant when drilling ferrous metals to reduce heat buildup and extend bit life. Dispose of worn or chipped bits according to applicable shop safety procedures.
