Hertel 2386449 Screw Machine Drill Bit Size 37 Hss

Product Description

The HERTEL 2386449 is a screw machine length drill bit designed for high-volume metal drilling in production and shop environments. Built from high-speed steel with an oxide coating, this bit cuts with a right-hand spiral flute and features a 135-degree split point with web thinning for reduced thrust and faster penetration on entry. At 1-13/16 inches overall length, it is shorter than jobber-length bits, making it well suited for tight clearances and rigid setups. The straight-cylindrical shank seats securely in standard drill chucks. This bit is sized at wire gauge 37, equivalent to 0.1040 inches in decimal.

Screw machine length drill bits like the 2386449 are standard tooling in machine shops, manufacturing cells, and production drilling operations. The shortened flute length of 13/16 inches provides added rigidity, reducing deflection when drilling in steel, aluminum, brass, and similar materials. It is commonly used in drill presses, CNC machining centers, and manual turret lathes where positional accuracy and hole quality are priorities. The oxide finish provides moderate lubricity and corrosion resistance during dry or lightly lubricated cutting.

Key Features

• Wire gauge size 37, 0.1040 inches decimal equivalent
• 135-degree split point with web thinning reduces walking and entry thrust
• High-speed steel construction handles a wide range of metals and alloys
• Oxide coating improves surface lubricity and resist light corrosion
• Screw machine length at 1-13/16 inches OAL for rigid, close-clearance drilling
• Straight-cylindrical shank compatible with standard drill chucks and collets

Compatibility

Designed as a standard screw machine length drill bit compatible with any drill press, machining center, turret lathe, or handheld drill using a chuck that accepts a 0.1040-inch straight-cylindrical shank.

Installation Notes

Installation of drill bits should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and de-energized before changing tooling. Seat the shank fully and evenly in the chuck or collet before tightening. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain hole quality.
