Walter-titex 7377210 Screw Machine Drill Bit 9.7 Mm

Product Description

The WALTER-TITEX 7377210 is a solid carbide screw machine length drill bit designed for high-performance drilling in cast iron and steel. Built to the DC160 series, it features a 9.7 mm diameter, a 140-degree X treme Evo point geometry, and a straight-cylindrical shank with a 10 mm shank diameter. The two-flute spiral design and Universal Advance performance rating make it well suited for demanding production environments. At 89 mm overall length with a 47 mm flute length, this bit delivers precision and rigidity in short-reach drilling applications. Conforms to DIN and ISO standards with a m7 diameter tolerance.

This drill bit is intended for use in screw machine length applications where shorter flute-to-diameter ratios (3xD) are required. It is suited for drilling cast iron and steel workpieces in shop environments such as machining centers, CNC mills, and drill presses. The straight-cylindrical shank allows direct chuck mounting without additional adapters. This bit does not include coolant-through capability, making it appropriate for setups where external coolant or dry cutting is used.

Key Features

• Solid carbide construction for wear resistance in ferrous materials
• 140-degree X treme Evo point geometry reduces thrust and improves self-centering
• Spiral two-flute design promotes chip evacuation in cast iron and steel
• Screw machine length (3xD flute ratio) provides rigidity in short-reach setups
• Straight-cylindrical shank compatible with standard drill chucks
• Meets DIN and ISO standards with m7 diameter tolerance for consistent fit

Compatibility

Designed for use in drilling cast iron and steel workpieces. Compatible with standard drill chucks and CNC toolholders accepting a 10 mm straight-cylindrical shank. Part of the WALTER-TITEX DC160 series.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians familiar with carbide cutting tools. Ensure the machine spindle and chuck are fully powered down and locked out before mounting or removing the bit. Solid carbide bits are brittle and should not be dropped or used for prying. Verify chuck concentricity and torque to the toolholder manufacturer specification before running; runout beyond acceptable limits will shorten tool life and compromise hole tolerance.
