Accupro 4500154 Solid Carbide Jobber Drill 3.80 Mm

Product Description

The ACCUPRO 4500154 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials. It measures 3.80 mm in diameter with an overall length of 2.9134 inches and a flute length of 1.4173 inches. The 140-degree split point and TiAlN coating make this bit well-suited for cutting through stainless steel and other hard alloys where heat buildup and edge wear are primary concerns. The R-thinned web reduces thrust requirements at the point. This bit is used by machinists and tool-and-die tradespeople in production and job-shop environments.

This jobber drill is intended for use in CNC machining centers, drill presses, and manual mills where a straight-shank carbide bit is required. Its 5xD flute-to-diameter ratio and coolant-through design support higher feed rates and longer tool life in stainless steel, hardened alloys, and similarly difficult workpiece materials. The right-hand cutting direction and regular spiral flute geometry suit standard spindle configurations. It is packaged and sold individually.

Key Features

• Solid carbide construction for rigidity and heat resistance in hard materials
• TiAlN coating extends tool life in stainless steel and high-temperature alloys
• 140-degree proprietary point reduces walking and improves entry accuracy
• R-thinned web lowers required drilling thrust at the point
• Coolant-through design supports chip evacuation and heat management at depth
• DIN-specification geometry for consistent dimensional compliance

Compatibility

Designed for use in standard straight-shank toolholders and drill chucks accepting a 6 mm shank diameter. Suitable for CNC and manual drilling applications targeting stainless steel and comparable hard-material workpieces within the 3.00 mm to 4.00 mm drill bit size range.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling. Secure the straight shank fully in a collet or drill chuck rated for the intended spindle speed before operation. Carbide bits are brittle compared to high-speed steel - avoid side loading, interrupted cuts without appropriate feed reduction, or dropping the tool on hard surfaces. Verify coolant flow is active before engaging the workpiece when using the through-coolant feature.
