Sgs 57018 Combo Drill Countersink Size 2 Solid Carbide Altin

Product Description

The SGS 57018 is a solid carbide combo drill countersink designed to perform drilling and countersinking in a single pass. Built to Series 301 standards, it features a 118-degree drill point angle and a 5/64 inch (0.0781 inch decimal) point diameter. The AlTiN coating provides heat resistance and extended tool life in demanding cutting applications. The double-end design and right-hand cut configuration make this a reliable choice for machinists and fabricators working across a wide range of materials. It is suited for production and job-shop environments where efficiency and tool longevity are priorities.

The SGS 57018 is rated for use on cast iron, stainless steel, steel, titanium, high temperature alloys, composites, non-ferrous metals, and plastics. The 60-degree included angle is standard for most countersinking applications in general machining, aerospace-adjacent fabrication, and precision metalworking. It is not an aircraft-style tool and is not tapered. The 47/64 inch shank length fits standard toolholders commonly found in CNC machining centers, drill presses, and manual mills.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN coating extends tool life under high heat and high-speed cutting conditions
• 118-degree drill point angle suits general-purpose drilling across multiple material types
• 60-degree included angle provides standard countersink geometry for flat-head fastener seating
• Double-end design allows the tool to be flipped when one end dulls, extending usable life
• Right-hand cut with plain cutting edge style for compatibility with standard spindle rotation

Compatibility

Designed as an OEM-style replacement and standard tooling option for machining operations requiring combined drilling and countersinking in a single tool. Compatible with standard toolholders accepting the 47/64 inch shank length.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool setup. Ensure the machine spindle is fully stopped and locked out before mounting or changing the tool. Verify toolholder runout and clamping torque per the machine manufacturer's guidelines before engaging the workpiece. Follow applicable shop safety standards and cutting fluid recommendations for the target workpiece material.
