Accupro 20393 Jobber Drill Bit 9/32 in Carbide Tin

Product Description

The ACCUPRO 20393 is a jobber-length twist drill bit designed for precision drilling in hard and abrasive materials. Built from solid carbide and coated with titanium nitride (TiN), it delivers extended tool life and reduced heat buildup compared to standard high-speed steel bits. The 150-degree split point reduces walking and allows drilling without a center punch in most applications. At 3 inches overall length with a 1.75-inch flute, this bit suits typical through-hole and blind-hole work in metal fabrication, machining, and maintenance environments. It is installed by machinists, tool and die technicians, and maintenance mechanics.

This drill bit is sized at 9/32 inch (0.2812 inch decimal) and fits within the 0.2500 to 0.3000 inch drill bit size range. It is suited for use in CNC machining centers, drill presses, and hand-held power drills with compatible chucks. The straight cylindrical shank seats securely in standard drill chucks. With a regular spiral and right-hand cutting direction, it is compatible with conventional drilling setups in metal, composites, and hard plastics.

Key Features

• Solid carbide construction for high hardness and wear resistance in demanding materials
• TiN coating reduces friction and extends cutting life between sharpenings
• 150-degree drill point angle minimizes walking and improves hole entry accuracy
• 3-flute geometry improves chip evacuation and surface finish in the hole
• Regular spiral type with right-hand cut for use in standard drilling equipment
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-style replacement and standard-fitment jobber drill bit for use in any drill press, CNC machining center, or hand-held power drill accepting a straight cylindrical shank in the 9/32 inch size range.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or trained maintenance technician. Secure the shank fully in the chuck and verify runout before drilling. Always power down and de-energize the drilling equipment before changing bits. Do not exceed the rated speed range for solid carbide tooling in the material being drilled, and use appropriate personal protective equipment including eye protection.
