Hertel 2386126 Screw Machine Drill Bit Size 5 Hss

Product Description

The HERTEL 2386126 is a screw machine length drill bit designed for high-speed, close-tolerance drilling in metal fabrication, machining, and production environments. Built from high-speed steel with an oxide coating, this bit features a 135-degree split point that self-centers on contact and reduces the need for a center punch. The web-thinned, parallel web configuration lowers thrust and improves chip evacuation. At 2.375 inches overall length, the stub-length body provides added rigidity over jobber-length bits, making it well suited for drill press and CNC turret work where runout and deflection are concerns. Installation is performed by machinists and toolroom technicians.

This drill bit is sized at wire gauge No. 5, equal to 0.2055 inches decimal. The straight-cylindrical shank seats directly into standard drill chucks, collets, and quick-change holders without adapters. Screw machine length bits are commonly used in production screw machine shops, sheet metal operations, and general metalworking where short-reach rigidity and consistent hole tolerance are required. The right-hand spiral flute design pulls chips up and out of the hole during drilling, reducing heat buildup at the cutting edge.

Key Features

• 135-degree split point self-centers and reduces walking on hard or smooth surfaces
• Web-thinned parallel web lowers cutting thrust and extends tool life
• High-speed steel construction with oxide finish for general-purpose metal drilling
• Stub screw machine length body increases rigidity versus standard jobber bits
• Right-hand regular spiral flute for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collets without adapters

Compatibility

Designed as a standard wire gauge No. 5 screw machine length drill bit compatible with any drill chuck, collet, or quick-change holder accepting a straight-cylindrical shank at the 0.2055 inch diameter range.

Installation Notes

This bit is installed and changed by machinists or toolroom technicians using standard chuck keys or collet wrenches. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank fully into the chuck or collet to the minimum recommended grip depth to prevent pullout under load. Use appropriate cutting fluid for the workpiece material to reduce heat and extend edge life.
