Accupro 50383 Solid Carbide Jobber Drill Bit 6.5 Mm

Product Description

The ACCUPRO 50383 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding materials. It features an ALTiN (aluminum titanium nitride) coating that increases surface hardness and heat resistance, extending tool life in ferrous metals, stainless steels, and hardened alloys. The 150-degree split point reduces walking and thrust force at entry. With a 3-flute spiral design and a 5xD flute-to-diameter ratio, it evacuates chips efficiently at higher feed rates. Overall length is 3.27 inches with a 1.50-inch flute length. This bit is intended for use in CNC machining centers, drill presses, and handheld power tools where carbide performance is required.

This jobber-length drill bit is suited for production and maintenance machining environments. It handles materials that would wear out high-speed steel tooling quickly, including hardened steel, cast iron, and heat-resistant alloys. The straight cylindrical shank fits standard drill chucks without adapters. It is sized in the 6.00 to 7.00 mm range, making it a common choice for metric fastener clearance holes and precision bores in manufacturing and fabrication shops.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• ALTiN coating increases heat resistance and extends tool life in ferrous and hardened alloys
• 150-degree point angle reduces entry thrust and minimizes workpiece walking
• 3-flute spiral design promotes fast chip evacuation at higher feed rates
• Straight cylindrical shank fits standard drill chucks without adapters
• Right-hand cutting direction, standard point type, no coolant-through requirement

Compatibility

Designed as a standard jobber-length drill bit in the 6.00 to 7.00 mm size range with a straight cylindrical shank, compatible with conventional drill chucks on CNC machining centers, drill presses, and handheld power tools conforming to ANSI specification standards.

Installation Notes

Installation and use should be performed by machinists or tool-and-die professionals familiar with carbide tooling. Secure the shank fully in the drill chuck and verify runout before beginning a cut, as carbide is brittle and sensitive to lateral loading. Do not use carbide drill bits in machines with excessive spindle play. Follow equipment manufacturer guidelines for feed rates and speeds appropriate to the workpiece material.
