Value Collection 01195734 Screw Machine Drill Bit 4.20mm

Product Description

The VALUE COLLECTION 01195734 is a cobalt screw machine length drill bit designed for drilling in tight clearance applications where a standard jobber-length bit is too long. At 4.20 mm (0.1654 inches) in diameter with a 55.00 mm (2.17 inches) overall length, this bit is built for rigidity and reduced deflection in short-reach setups. The 135-degree split point geometry allows self-centering on contact, eliminating the need for a center punch on most materials. Two regular-spiral flutes clear chips efficiently during drilling operations. The heavy-duty cobalt construction handles harder workpiece materials and elevated heat better than standard high-speed steel bits.

Screw machine length drill bits are used in drill presses, CNC machines, lathes, and hand-held power drills where reduced length improves stability or where spindle clearance is limited. This bit is well suited for production drilling in metal fabrication, maintenance and repair, and mechanical assembly environments. The straight shank fits standard drill chucks. The right-hand cutting direction is standard for conventional drilling operations. The straw finish is a light heat-treatment coating that provides modest lubricity and corrosion resistance.

Key Features

• 4.20 mm (0.1654 inch) diameter with a short 55.00 mm (2.17 inch) overall length for rigidity in tight setups
• 135-degree split point self-centers on contact and reduces walking without a center punch
• Cobalt construction provides heat resistance for drilling harder and abrasive materials
• Two regular-spiral flutes for efficient chip evacuation
• Heavy-duty grade classification for demanding production and repair applications
• Straight shank fits standard drill chucks without adapters

Compatibility

Designed as a standard screw machine length drill bit with a straight shank for use in any drill press, CNC spindle, lathe tailstock, or hand-held drill chuck accepting bits in the 3.50 mm to 5.00 mm (0.1500 to 0.2000 inch) size range.

Installation Notes

Installation is performed by machinists, tool and die workers, and maintenance technicians. Secure the straight shank fully in the drill chuck and verify concentricity before drilling. Power down and de-energize the machine before changing bits. Do not exceed the recommended speed and feed for the workpiece material when using cobalt bits, and use appropriate cutting fluid where the material and application call for it.
