Value Collection 01290451 Screw Machine Drill Bit 1mm Hss

Product Description

The VALUE COLLECTION 01290451 is a screw machine length drill bit designed for precision drilling in metalworking, maintenance, and light fabrication applications. Built from high-speed steel (HSS) with an oxide coating for improved wear resistance and heat dissipation, this bit measures 1.00 mm in diameter with an overall length of 26.00 mm (approximately 1.024 inches). The 118-degree standard point angle is suited for drilling into mild steel, aluminum, plastics, and similar materials. Its compact screw machine length provides added rigidity and reduced deflection compared to jobber-length bits, making it well-suited for use in tight spaces or drill press work.

This drill bit is used in machine shop environments, maintenance and repair operations, and precision assembly work where small-diameter, close-tolerance holes are required. The straight cylindrical shank accepts standard drill chucks without modification. The right-hand cutting direction and regular spiral flute geometry promote consistent chip evacuation during drilling. Machinists, tool-and-die technicians, and industrial maintenance professionals are the typical end users for this size and style of bit.

Key Features

• 1.00 mm diameter with a 118-degree standard point angle for general-purpose drilling
• High-speed steel construction provides durability across common work materials
• Oxide coating improves surface hardness and reduces friction at the cutting edge
• Screw machine length (26.00 mm OAL) delivers greater rigidity and reduced deflection vs. jobber length
• Regular spiral flute geometry promotes effective chip evacuation
• Web-thinned construction reduces thrust required at entry
• Straight cylindrical shank fits standard drill chucks

Compatibility

Designed as a general-purpose replacement or stock drill bit for use in standard drill chucks accepting straight cylindrical shanks in the 0.00 to 3.50 mm drill bit size range.

Installation Notes

This bit is installed and replaced by machinists or maintenance technicians using a standard drill chuck key or keyless chuck. Secure the shank fully in the chuck before operation to prevent runout or slippage. For extended service life, use cutting fluid or a suitable lubricant when drilling ferrous metals. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed, as a compromised edge on a small-diameter bit increases the risk of breakage.
