Precision Twist Drill 5996462 9/32 in Extra Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5996462 is a 9/32 inch diameter extra length drill bit engineered for deep-hole drilling in metalworking and fabrication applications. Built from high-speed steel with a bright uncoated finish, it features a 135-degree split-point tip that reduces walking and requires no center punch on most materials. The parabolic flute geometry accelerates chip evacuation in deep cuts, reducing heat buildup and the need for frequent peck cycles. With a 9 inch flute length and 12 inch overall length, this bit reaches depths that standard-length drills cannot. It is a right-hand cutting bit with a straight cylindrical shank and web-thinned, tapered web construction for reduced thrust.

This extra length drill bit is suited for machine shops, fabrication facilities, and maintenance operations where standard drill lengths fall short. It handles a wide range of workpiece materials and fits any drill press, CNC machining center, or hand drill with a compatible chuck. The QC1290P series targets applications requiring extended reach with consistent hole quality.

Key Features

• 135-degree split-point tip reduces walking and eliminates center-punch requirement on most materials
• Parabolic flute design promotes fast chip evacuation in deep-hole applications
• Web-thinned tapered web reduces axial thrust and extends bit life
• High-speed steel construction withstands the heat generated in extended drilling cycles
• 12 inch overall length with 9 inch flute length provides reach beyond standard jobber bits
• Right-hand cutting, straight cylindrical shank fits standard drill chucks and collets

Compatibility

Compatible workpiece materials include alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, graphite, hardened steel, magnesium, magnesium alloy, malleable iron, nickel, stainless steel, structural steel, tempered steel, thermoplastics, and thermosetting plastics.

Installation Notes

Install in a drill press, milling machine, or hand drill with a chuck rated for straight cylindrical shanks of the appropriate diameter. Power down and lock out the machine before securing or changing bits. Use cutting fluid or coolant appropriate to the workpiece material to manage heat, particularly in stainless steel, hardened steel, and cast iron. Do not exceed the spindle speed recommended for the material and bit diameter.
