Accupro 4500200 Solid Carbide Jobber Drill 19/64 in Dlc

Product Description

The ACCUPRO 4500200 is a solid carbide jobber-length drill bit designed for precision drilling in aluminum and non-ferrous materials. It carries a DLC (Diamond-Like Carbon) coating that reduces friction and extends tool life in high-cycle applications. The 118-degree point angle suits general-purpose entry into soft metals and composites. At 4.6406 inches overall length with a 2.5156-inch flute length, this bit fits standard jobber-length applications in CNC machining centers and manual drill presses alike. Coolant-through capability supports chip evacuation during deep-hole operations. It is sized at 19/64 inch (0.2969 inch decimal) with a 5/16-inch straight cylindrical shank, and is intended for installation by machinists and tool-and-die professionals.

This drill bit is suited for production and maintenance machining environments where aluminum, copper, brass, and other non-ferrous workpieces are common. The DLC coating and solid carbide substrate make it appropriate for both wet and dry cutting conditions in CNC turning centers, vertical machining centers, and benchtop drill presses. The 5xD flute-to-diameter ratio and regular spiral flute geometry support consistent chip flow across a range of feed and speed settings.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous materials
• DLC coating reduces friction and extends cutting edge life
• 118-degree proprietary point angle for accurate entry and reduced walking
• Coolant-through design aids chip evacuation in deep-hole drilling
• Right-hand cutting, regular spiral flute with 5xD flute-by-diameter ratio
• Straight cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

Designed for use in standard drill chucks and collet toolholders accepting a 5/16-inch straight shank. Primary workpiece material compatibility is aluminum and non-ferrous metals per manufacturer specification.

Installation Notes

This tool is installed and changed by machinists following standard toolroom procedures. Always power down and lock out the spindle before changing tooling. Secure the shank fully within the chuck or collet to the manufacturer-recommended engagement depth to prevent pullout under load. Do not exceed the drill press or machining center spindle speed rating for the selected tool diameter and material.
