8020, 6060, 15 Series 13/16″ Counterbore Cutter High Speed Steel Drill Bit 80/20 Aluminum T-Slot Extrusion Tool

Description

Product Overview

This 13/16″ High Speed Steel (HSS) Counterbore Cutter is engineered for use with 80/20 Aluminum T-Slot Extrusion systems. Made from durable HSS material, it delivers precision and longevity in demanding industrial environments. The cutter’s specially ground geometry ensures clean cuts and reduced tool wear during repetitive operations. Designed to fit standard drill press setups or CNC machines, this bit is ideal for fabrication shops, makerspaces, and engineering labs requiring consistent counterboring performance.

Usage

This tool excels in applications involving aluminum T-slot extrusions such as custom workbenches, modular enclosures, or structural frames. It is commonly used by engineers, machinists, and DIY builders who need to create flush holes for fasteners or mounting hardware. The cutter performs best with standard drill chucks and can be integrated into automated systems for high-volume production. Its compact size allows it to fit in tight spaces while maintaining cutting accuracy.
