Hertel 2386423 Screw Machine Drill Bit Size 35 Hss

Product Description

The HERTEL 2386423 is a screw machine length drill bit designed for high-production drilling in metal, plastic, and similar materials. It measures 0.1100 inches (7/64 inch, wire size 35) in diameter with an overall length of 1.875 inches and a flute length of 0.875 inches. The bit features a 135-degree split point for fast engagement and reduced walking on contact, and is ground from high-speed steel with an oxide finish that provides baseline lubricity and corrosion resistance. The shortened body length of a screw machine drill increases rigidity and reduces deflection compared to jobber-length bits, making it a standard choice for production and screw machine work.

This bit is suited for use in turret lathes, CNC screw machines, drill presses, and handheld power tools where a stubby, rigid drill is required. The straight-cylindrical shank accepts standard drill chucks without adapters. It is commonly used in metalworking shops, maintenance environments, and light manufacturing for close-tolerance hole sizing in ferrous and non-ferrous metals as well as thermoplastics.

Key Features

• 135-degree split point reduces thrust force and eliminates center-punching on most metals
• Web-thinned parallel web maintains strength while lowering cutting resistance
• High-speed steel construction withstands heat generated in production drilling cycles
• Oxide coating provides light surface protection and reduces chip welding
• Screw machine length body increases rigidity and minimizes deflection in deep setups
• Right-hand spiral flute with straight-cylindrical shank for universal chuck compatibility

Compatibility

Designed as a standard screw machine length drill bit for use in any drill chuck or collet accepting a 0.1100-inch straight-cylindrical shank.

Installation Notes

Installation and use of this bit should be performed by machinists or trained trade personnel familiar with drilling operations. Secure the shank fully in the chuck and verify runout before beginning a drilling cycle. Always power down or de-energize the machine and bring the spindle to a complete stop before changing bits. Do not exceed the recommended RPM range for the material being drilled or the bit diameter.
