Accupro 4500292 Carbide Jobber Drill 7/32 in Dlc 118 Deg

Product Description

The ACCUPRO 4500292 is a solid carbide jobber-length drill bit designed for precision hole-making in aluminum and non-ferrous materials. It features a DLC (Diamond-Like Carbon) coating that reduces friction and extends tool life in high-speed production environments. The 118-degree split point geometry provides accurate starting without a center punch. At 3.9375 inches overall length with a 1.8906-inch flute length, this bit fits standard drill chucks via its 0.2344-inch straight cylindrical shank. Coolant-through capability makes it suitable for CNC machining centers where through-spindle coolant is available. Machinists, toolroom technicians, and CNC operators are the primary users.

This drill bit is sized at 7/32 inch (0.2188 inches decimal) and falls within the 0.2000 to 0.2500 inch drill bit size range. It is suited for drilling aluminum, copper, brass, and other non-ferrous materials in both job shop and production settings. The 5xD flute-to-diameter ratio supports deeper hole applications without excessive chip packing. The ISO specification designation means it meets internationally recognized dimensional standards, making it a reliable drop-in for CNC programs already dimensioned to ISO tooling. Right-hand cutting direction is standard for conventional spindle rotation.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous applications
• DLC coating reduces built-up edge and extends service life in aluminum drilling
• 118-degree proprietary point for accurate self-starting entry
• Coolant-through design compatible with CNC spindle coolant systems
• 5xD flute-to-diameter ratio supports deeper hole depths with efficient chip evacuation
• Straight cylindrical shank fits standard ER collets and drill chucks without modification

Compatibility

Designed for use in CNC machining centers, drill presses, and hand-held drilling equipment with standard straight-shank tool holders or ER collet systems. Primary workpiece materials are aluminum and non-ferrous metals. ISO specification designation confirms dimensional compliance for use in ISO-toleranced toolholding systems.

Installation Notes

Installation and operation should be performed by qualified machinists or CNC technicians familiar with cutting tool runout tolerances and spindle speeds appropriate for carbide tooling. Ensure the spindle is fully stopped and the machine is in a safe state before loading or changing the drill bit. Verify collet or chuck bore matches the 0.2344-inch shank diameter to avoid runout that can chip carbide. When using coolant-through capability, confirm coolant pressure and flow rate are within the machine spindle specifications before initiating a cut.
