Precision Twist Drill 6000217 Extra Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000217 is an extra length, high speed steel (HSS) drill bit designed for deep-hole drilling applications across a range of materials. The bit measures 0.2969 inches in diameter with a 12-inch overall length and a 9-inch spiral flute length, giving it the reach needed for applications where standard-length bits fall short. It features a 118-degree standard drill point angle, right-hand cutting direction, and a straight-cylindrical shank for use in standard chucks. The uncoated HSS construction and web-thinned, tapered web configuration make it suitable for general-purpose production and maintenance work performed by machinists, tool and die tradespeople, and mechanical contractors.

This Series 1290 drill bit is built for use in drilling operations where extended reach into deep features or thick stock is required. Primary workpiece materials include aluminum, magnesium, copper, nickel, synthetic materials, and titanium. Secondary workpiece materials include stainless steel, steel, hardened steel, malleable iron, high strength bronze, nickel alloys, magnesium alloys, and reinforced plastics. The bit's 12xD flute-by-diameter ratio supports chip evacuation over its extended reach, reducing the need for frequent peck cycles in many applications.

Key Features

• 9-inch spiral flute length supports chip clearance in deep-hole operations
• 118-degree standard point angle suitable for general-purpose drilling
• Web-thinned, tapered web configuration reduces thrust and improves point geometry
• Right-hand cutting, straight-cylindrical shank fits standard drill chucks
• Uncoated high speed steel construction; ANSI standard compliant

Compatibility

Designed as an OEM-style general-purpose extra length drill bit compatible with standard straight-shank chucks. Rated for use in aluminum, magnesium, copper, nickel, synthetic materials, titanium, stainless steel, steel, hardened steel, malleable iron, high strength bronze, nickel alloys, magnesium alloys, and reinforced plastics per Series 1290 specifications.

Installation Notes

This bit is installed by machinists or qualified tradespeople using drill presses, milling machines, or hand-held power drills equipped with appropriately sized chucks. Ensure the workpiece is securely clamped before drilling and that the bit is fully seated and tightened in the chuck. Use appropriate cutting fluid or coolant as required by the workpiece material, and reduce feed pressure when breaking through to prevent bit walking or workpiece damage. Follow applicable shop safety and ANSI B11 machine tool safety guidelines.
