Guhring 9065090039700 Extra Length Carbide Drill Bit

Product Description

The GUHRING 9065090039700 is a solid carbide extra length drill bit engineered for deep hole drilling in demanding industrial and machining applications. It features a TiAlN coating, a 135-degree drill point angle with RT100 T point geometry, and web-thinned construction for reduced thrust and improved chip evacuation. The spiral flute design and straight-cylindrical shank keep the bit stable and centered throughout the cut. With a flute-to-diameter ratio of 15xD and a maximum drilling depth of 2.758 inches, this bit handles deep-hole work that standard-length drills cannot reach. It is installed and used by machinists, tool-and-die professionals, and CNC operators working in production or job-shop environments.

This drill bit is designed for cutting cast iron, stainless steel, and steel as primary workpiece materials, with secondary capability in aluminum and titanium alloy. The Series 6509 is a high-performance line built for deep-hole drilling where coolant-through capability is required to manage heat and chip removal. Typical install scenarios include CNC machining centers, drill presses, and manual mills where through-spindle or external coolant is available. The h7 shank diameter tolerance ensures consistent fit in standard collets and chucks.

Key Features

• Solid carbide construction with TiAlN coating for extended tool life in ferrous and exotic materials
• 135-degree RT100 T drill point with web thinning for reduced entry force and accurate positioning
• Coolant-through design supports effective chip evacuation in deep-hole operations
• 15xD flute-to-diameter ratio enables drilling depths up to 2.758 inches
• Right-hand cutting, spiral flute with regular spiral type for consistent chip flow
• h7 shank diameter tolerance for precise fit in collets and drill chucks

Compatibility

Designed as an OEM-style replacement and production tooling option for deep-hole drilling applications in CNC machining centers and drill presses compatible with straight-cylindrical shank tooling in the Series 6509 line.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or CNC operators familiar with tooling setup and speeds-and-feeds for solid carbide drills. Verify spindle runout and collet condition before seating the bit, as solid carbide is sensitive to lateral stress. Coolant-through capability should be active during deep-hole operations to prevent heat buildup and chip packing. Refer to the machine tool manufacturer and GUHRING cutting data recommendations for appropriate spindle speeds and feed rates for the target workpiece material.
