Accupro 10387 Solid Carbide Jobber Drill Bit 17/64 in

Product Description

The ACCUPRO 10387 is a solid carbide jobber length drill bit designed for precision hole-making in demanding machining applications. It measures 17/64 inches (0.2656 inches) in diameter with an overall length of 3.5 inches and a flute length of 1.5 inches. The 150-degree drill point angle and 3-flute spiral design promote fast chip evacuation and reduced cutting resistance. The bright, uncoated finish suits general-purpose use across a range of workpiece materials. Right-hand cutting direction and a straight cylindrical shank allow straightforward installation in standard drill chucks and CNC tool holders.

This drill bit is suited for production and maintenance machining environments where accuracy and tool life in hard or abrasive materials are priorities. The 3-flute geometry increases chip clearance compared to standard 2-flute designs, making it a practical choice for machinists, tool-and-die shops, and industrial maintenance technicians drilling into steel, stainless, cast iron, or similar materials. The jobber length profile balances reach and rigidity for a wide range of drilling depths in both manual and CNC setups.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• 17/64 inch (0.2656 inch) diameter with 150-degree standard point angle for clean entry and reduced walking
• 3-flute spiral design improves chip evacuation over conventional 2-flute jobber bits
• Right-hand cutting direction with straight cylindrical shank for compatibility with standard chucks and collets
• Bright, uncoated finish suitable for general-purpose and dry drilling applications
• ANSI specification designation ensures consistent dimensional standards

Compatibility

Designed as an OEM-style replacement or direct addition for standard jobber length drill bit applications; straight cylindrical shank fits conventional 3-jaw drill chucks, ER collet systems, and CNC tool holders accepting a 17/64 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or trained technician. Ensure the machine spindle is fully powered down and locked out before inserting or removing the bit from the chuck or collet. Verify chuck or collet runout is within acceptable tolerance before use, as excessive runout accelerates carbide wear and may cause premature breakage. Do not use this bit for interrupted cuts or hammer-drill applications; carbide is brittle and is not designed to absorb impact loading.
