Guhring 9006180061000 Cobalt Extra Length Drill Bit

Product Description

The GUHRING 9006180061000 is a Series 618 extra length cobalt drill bit designed for deep hole drilling applications in demanding production and job shop environments. Built from high-performance cobalt tool steel with an uncoated finish, it delivers consistent performance in materials where heat and wear resistance are critical. The bit measures 0.2402 inches in diameter with an overall length of 8.465 inches and a parabolic flute running 5.906 inches, allowing for efficient chip evacuation at extended reach. A web-thinned, tapered web configuration reduces thrust and improves penetration. Licensed machinists, toolroom technicians, and CNC operators will find this bit well-suited for precision deep-hole work.

This drill bit is engineered for deep hole drilling at a 15xD flute-to-diameter ratio, reaching a maximum drilling depth of 5.545 inches. Primary workpiece materials include aluminum and titanium alloy, with secondary suitability for steel. The straight-cylindrical shank with a 0.2402-inch shank diameter seats securely in standard drill chucks and collet holders. The 130-degree point angle and right-hand cutting direction make it a practical choice for production drilling where extended reach and accurate entry are required.

Key Features

• Cobalt tool steel construction for elevated heat and wear resistance
• Parabolic flute geometry promotes rapid chip evacuation in deep holes
• Web-thinned tapered web reduces cutting thrust and improves penetration
• 130-degree point angle with standard point type for accurate entry
• 15xD flute-to-diameter ratio supports deep hole drilling up to 5.545 inches
• Straight-cylindrical shank fits standard drill chucks and collet holders

Compatibility

Designed for use in aluminum, titanium alloy, and steel workpieces as an extra length deep hole drill per DIN 1869 specification. Suitable for applications where standard-length drills cannot reach required depth.

Installation Notes

This drill bit is installed and operated by machinists and toolroom technicians on drill presses, machining centers, and CNC equipment. Secure the straight-cylindrical shank fully in a properly sized chuck or collet before operation. Confirm spindle speed and feed rate are appropriate for the workpiece material and hole depth before engaging the cut. No coolant-through capability is present on this bit, so external coolant or cutting fluid application is recommended when drilling deep holes in metal.
