Hertel 16704793 Drill Bit Size 43 Solid Carbide 135 Degree

Product Description

The HERTEL 16704793 is a screw machine length drill bit designed for precision drilling in demanding industrial and trade applications. Built from solid carbide, this bit handles difficult workpiece materials where high-speed steel tooling falls short. The 135-degree split-point tip reduces walking and allows for clean entry without a center punch. At 0.0890 inches in diameter (wire gauge size 43) and 1.75 inches overall length, this short-series bit delivers rigidity and accuracy in tight setups and automated equipment. Two slow-spiral flutes evacuate chips efficiently in the materials this bit is engineered to cut.

This drill bit is suited for use in CNC machining centers, screw machines, drill presses, and hand-held drilling operations where controlled, accurate holes are required. The straight cylindrical shank seats directly into standard drill chucks and collet holders without modification. Its screw machine length geometry makes it a practical choice in applications where clearance is limited or where a stub-length bit reduces deflection. The bright uncoated finish is appropriate for use with cutting fluids or dry cutting depending on the workpiece material.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive workpiece materials
• 135-degree split-point tip reduces thrust force and eliminates the need for center-punching
• Slow-spiral flute geometry promotes chip control in cast iron, stainless steel, titanium alloy, nickel alloy, and tool steel
• Screw machine (stub) length improves rigidity and reduces deflection compared to jobber-length bits
• Straight cylindrical shank fits standard drill chucks and collet tool holders
• Bright uncoated finish compatible with a wide range of cutting fluids

Compatibility

Designed as a direct-fit replacement or production drill bit for applications requiring a wire gauge size 43 (0.0890 inch) hole in cast iron, nickel alloy, stainless steel, titanium alloy, or tool steel workpieces.

Installation Notes

Installation and use of this drill bit should be performed by machinists or qualified trade professionals familiar with cutting tool setup and machine operation. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify shank seating and runout before beginning a cut, as solid carbide is brittle and susceptible to breakage from misalignment or side loading. Use appropriate cutting fluid for the workpiece material to manage heat and extend tool life.
