Cleveland C89468 Jobber Drill Bit 3/16 in Solid Carbide

Product Description

The CLEVELAND C89468 is a solid carbide jobber-length drill bit designed for precision drilling in ferrous materials. Built to ASME B94.11M standards, it features a 140-degree four-facet point that reduces walking and improves entry accuracy on hard surfaces. The straight flute geometry supports chip evacuation in short-hole applications and keeps the cut clean in cast iron and steel workpieces. At 2.1875 inches overall length with a 1.125-inch flute length, this bit fits standard drill chucks without adapters. Licensed machinists, tool-and-die technicians, and shop professionals routinely use this size for tapping prep, clearance holes, and precision fixture work.

The C89468 is suited for production and maintenance drilling in cast iron and steel. Its 3/16-inch diameter and straight flute design make it a practical choice for short-depth holes where chip packing is a concern. The bright, uncoated finish is appropriate for use with cutting fluids and does not add dimensional buildup to the cutting edge. Maximum drilling depth is 0.6563 inches, keeping this bit in its optimal performance envelope for shallow-hole operations in ferrous stock.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• 140-degree four-facet point reduces drill walk and improves hole entry accuracy
• Straight flute design promotes chip clearance in cast iron and steel
• Bright, uncoated finish compatible with water-soluble and oil-based cutting fluids
• Tapered web configuration adds strength behind the cutting edge
• Meets ASME B94.11M dimensional standards for jobber-length drill bits

Compatibility

Designed for drilling cast iron and steel workpieces; primary workpiece materials as specified by the manufacturer are cast iron and steel. Coolant-through capability is not supported on this bit.

Installation Notes

Secure the bit fully in the chuck before operation and verify runout with a dial indicator when tight tolerances are required. Solid carbide bits are brittle compared to high-speed steel and should not be used in hand-held drills or setups with excessive vibration. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality. Do not exceed the rated maximum drilling depth of 0.6563 inches without retracting to clear chips.
