Walter-titex 7377171 Screw Machine Drill Bit 8.1mm Carbide

Product Description

The WALTER-TITEX 7377171 is a solid carbide screw machine length drill bit engineered for precision drilling in demanding trade and industrial applications. Built to the DC160 series standard, this bit features a 140-degree X treme Evo point geometry that supports fast, accurate entry with reduced thrust force. The 8.1 mm diameter corresponds to 0.3189 decimal inches, and the overall length is 89 mm (3.5039 inches). With a right-hand spiral flute design and a coated finish, the 7377171 delivers consistent performance in cast iron and steel workpieces. Licensed machinists, maintenance techs, and skilled tradespeople working with precision metalwork will find this bit suited to high-tolerance production and service drilling tasks.

This drill bit is designed for screw machine length applications where a compact, rigid tool is needed in confined or production-line setups. It is well-suited for drilling cast iron and steel in both shop environments and field maintenance scenarios. The 3xD flute-by-diameter ratio and 47 mm flute length support chip evacuation in moderate-depth holes up to 35 mm. The straight-cylindrical shank with a 10 mm diameter fits standard drill chucks and collet holders used in CNC machining centers, drill presses, and portable power tools.

Key Features

• 140-degree X treme Evo point for clean entry and accurate positioning in ferrous materials
• Solid carbide construction for high rigidity and extended tool life in cast iron and steel
• Coated finish reduces friction and improves wear resistance at the cutting edge
• Right-hand spiral flutes promote efficient chip removal during through and blind hole drilling
• Straight-cylindrical 10 mm shank compatible with standard chucks and collet systems
• Conforms to DIN and ISO dimensional standards for consistent fit and interchangeability

Compatibility

Designed as an OEM-style replacement or direct-application drill bit for use in standard drill chucks and collet holders accepting a 10 mm straight-cylindrical shank, suitable for cast iron and steel workpiece materials as specified by the manufacturer.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tradespeople familiar with rotary cutting tool safety. Always ensure the machine spindle is fully stopped and power is disconnected before changing or inspecting the bit. Secure the shank firmly in the chuck or collet to the tool manufacturer's specified holding depth before beginning any drilling operation. Follow applicable shop safety standards and wear appropriate PPE, including eye protection, when operating drilling equipment.
