Value Collection 01292457 Drill Bit 4.00 Mm Hss 118 Deg

Product Description

The VALUE COLLECTION 01292457 is a screw machine length drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high-speed steel (HSS) with an oxide coating for added wear resistance, this bit features a standard 118-degree split point and a regular spiral flute for efficient chip evacuation. The straight cylindrical shank seats securely in standard drill chucks. At 55.00 mm (2.17 inches) overall length and a 22.00 mm flute length, this stub-length format offers added rigidity compared to jobber-length bits, reducing deflection in short-hole applications. Right-hand cutting direction. Intended for use by machinists, maintenance technicians, and trade professionals working on production or repair operations.

This drill bit is suited for light to medium drilling tasks in ferrous and non-ferrous metals, plastics, and composite materials. The screw machine (stub) length format is commonly used in drill presses, CNC machines, hand-held power drills, and turret lathes where clearance is limited or rigidity is critical. The 4.00 mm diameter (0.1575 inch) falls within the 3.50 mm to 5.00 mm size range, making it appropriate for tapping pilots, clearance holes, and precision work requiring consistent hole quality.

Key Features

• High-speed steel (HSS) construction for durability across general-purpose drilling applications
• Oxide coating improves surface hardness and provides basic lubricity during cutting
• 118-degree standard point angle suited for most common materials
• Stub screw machine length (55.00 mm OAL) reduces deflection and improves hole accuracy
• Web-thinned geometry reduces thrust force and improves cutting efficiency
• Straight cylindrical shank compatible with standard drill chucks and collets
• Right-hand, 2-flute regular spiral design for effective chip removal

Compatibility

Designed as a general-purpose replacement or stock bit for use in standard drill presses, CNC drilling machines, hand-held power drills, and turret lathes accepting a straight cylindrical shank. Compatible with any chuck or collet sized for a 4.00 mm shank diameter.

Installation Notes

Secure the shank fully in the chuck or collet before operation and verify the bit runs true with minimal runout. Use appropriate cutting fluid or coolant when drilling hardened or abrasive materials to extend tool life. Follow machine manufacturer guidelines for spindle speed based on material and bit diameter. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged to avoid oversized or irregular holes.
