Walter-titex 7377075 Screw Machine Drill Bit 4.1mm Carbide

Product Description

The WALTER-TITEX 7377075 is a solid carbide screw machine length drill bit designed for precision drilling in cast iron and steel. Built to the DC160 series specification, it features a 140-degree X treme Evo point geometry that supports fast penetration and accurate hole entry without a center punch. At 4.1 mm in diameter (0.1614 inches decimal equivalent) with a 6.0 mm straight-cylindrical shank, the bit is compatible with standard collet and chuck toolholding setups. With a total length of 66.0 mm (2.5984 inches) and a 24.0 mm spiral flute, it delivers consistent chip evacuation in short-hole drilling applications. Installed by machinists and precision fabricators in production and maintenance environments.

This bit is suited for screw machine length drilling operations in cast iron and steel workpieces. The 3xD flute-to-diameter ratio and Universal Advance performance rating make it appropriate for general-purpose production drilling where hole accuracy and surface finish consistency are required. The 17.0 mm maximum drilling depth and right-hand cut direction are standard for CNC machining centers, drill presses, and manual lathes equipped for small-diameter work. Coated finish extends tool life in abrasive and harder ferrous materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• 140-degree X treme Evo point type for accurate self-centering entry
• 6.0 mm straight-cylindrical shank fits standard collet chucks
• 2-flute spiral design promotes chip evacuation in short drilling depths
• Coated finish extends cutting life in cast iron and steel
• Conforms to DIN and ISO dimensional standards

Compatibility

Designed as an OEM-style screw machine length drill bit for use in cast iron and steel; compatible with standard toolholding systems accepting a 6.0 mm straight-cylindrical shank. Fits drill size range applications from 3.50 mm to 5.00 mm (0.1500 to 0.2000 inches decimal).

Installation Notes

Installation is performed by machinists or tool and die technicians. Secure the shank fully in a collet or drill chuck rated for the shank diameter before operating. Power down or e-stop the machine and confirm zero spindle rotation before changing or inspecting the bit. Do not exceed the 17.0 mm maximum drilling depth; breakthrough cuts in thin stock should be supported to prevent grabbing on exit.
