Walter-titex 7462144 Carbide Drill Bit 3/8 Inch DC150

Product Description

The WALTER-TITEX 7462144 is a solid carbide jobber length drill bit designed for precision drilling in demanding production and maintenance environments. Built on the DC150 series platform, this bit features a 140-degree drill point angle, TiNAl coating, and a right-hand spiral flute configuration. The 3/8 inch (0.3750 inch) diameter is held to an m7 tolerance, making it suitable for applications where hole size consistency is critical. Manufactured from WJ30TA-grade carbide, it handles cast iron and steel workpieces across blind hole and stack drilling operations. Machinists, tool and die technicians, and production drillers are the primary installers of this tool class.

This drill bit is rated for use in cast iron (material code K) and steel (material code P) workpieces. It is well suited for blind hole drilling and stack drilling applications in both shop and field production settings. The 5xD flute-to-diameter ratio provides chip clearance in deeper cuts. With a maximum drilling depth of 49.00 mm and an overall length of 103.00 mm, this bit fits standard drill chucks and machining center toolholders accepting a 10.00 mm straight-cylindrical shank. Coolant-through capability is not supported on this configuration.

Key Features

• Solid carbide WJ30TA-grade construction for rigidity and wear resistance in ferrous materials
• TiNAl coating extends tool life in cast iron and steel cutting applications
• 140-degree drill point angle reduces thrust force and improves centering on entry
• Right-hand spiral flute with 5xD ratio promotes chip evacuation in blind hole drilling
• m7 diameter tolerance ensures consistent hole size for close-tolerance work
• Straight-cylindrical shank with 10.00 mm diameter fits standard chuck and collet toolholding systems

Compatibility

Designed for use in cast iron and steel workpieces as identified by primary workpiece material codes K and P. Suitable for blind hole and stack drilling tool applications conforming to ANSI and ISO standards within the DC150 series drill bit family.

Installation Notes

Install and remove drill bits only with the machine powered down and spindle fully stopped. Verify the toolholder or chuck is properly rated for the 10.00 mm shank diameter before securing the bit. Follow machine manufacturer runout and clamping torque guidelines for the toolholding system in use. Do not use this bit for coolant-through setups, as this configuration does not support internal coolant delivery.
