Guhring 9041070250050 Replaceable-tip Drill 0.984-1.004 in

Product Description

The GUHRING 9041070250050 is a replaceable-tip drill body designed for precision hole-making in metalworking and machining applications. Built on the Series 4107 platform, this drill accepts HT 800 WP insert tips and features through-coolant capability for extended tool life and improved chip evacuation at depth. The steel body has a 25.4 mm shank diameter and an overall length of 180 mm, with a maximum drill depth of 81.3 mm. It covers a diameter range of 0.984 to 1.004 inches, making it suited for applications requiring tight bore tolerances in a 3xD depth configuration.

This drill body is used in CNC machining centers and turning centers where repeatable, high-productivity drilling is required. The replaceable-tip design reduces per-hole tooling cost by allowing insert changes without replacing the full body. Typical applications include drilling in steel, cast iron, and similar ferrous materials in both job shop and production environments. The through-coolant feature supports consistent performance at the rated maximum depth of 81.3 mm, particularly in deep-hole or high-feed drilling cycles.

Key Features

• Accepts HT 800 WP replaceable insert tips — body can be reused across multiple tip changes
• Through-coolant design supports chip evacuation and thermal management at full drilling depth
• 3xD toolholder style rated to 81.3 mm maximum drill depth
• Diameter range of 0.984 to 1.004 inches accommodates near-inch bore applications
• 120 mm flute length provides clearance for chip flow over the full usable depth range
• Steel body construction offers rigidity for demanding drilling operations

Compatibility

Designed for use with HT 800 WP series insert tips in the GUHRING Series 4107 replaceable-tip drill system. Compatible insert style is HT 800 WP as specified by the manufacturer.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine fully powered down and in a safe, locked-out state. The insert tip should be seated and torqued according to the toolholder manufacturer's specifications using the appropriate insert key. Verify coolant supply line compatibility before mounting, as this body requires through-spindle or through-tool coolant for rated performance. Confirm shank interface and retention system compatibility with the machine spindle before use.
