Osg 750016216 Combo Drill Reamer 0.1615 in Solid Carbide

Product Description

The OSG 750016216 is a solid carbide combo drill reamer designed to drill and ream in a single operation. It produces a finished bore to a reamer size of 0.1615 inches (4.10 mm) with a right-hand spiral and right-hand cutting direction. The diamond coating provides extended tool life in abrasive and hard materials. With a 1.581-inch flute length and a 6-inch overall length, this tool is suited for precision hole-finishing work in machining environments. It is installed and operated by machinists and tooling technicians on CNC machining centers and manual mills requiring tight bore tolerances.

This combo drill reamer is intended for applications where a separate drilling and reaming sequence would otherwise be required. The cylindrical shank diameter of 0.1615 inches allows direct chucking in standard collet systems. The diamond coating makes it well suited for composite materials, ceramics, and other abrasive workpiece materials where uncoated carbide tools wear prematurely. It is a single-pass solution for small-diameter precision bores in production and job-shop environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Diamond coating extends cutting edge life in composites, ceramics, and abrasive alloys
• Combo drill-reamer design completes drilling and reaming in one tool pass
• Right-hand spiral and right-hand cutting direction for standard CNC and manual mill spindles
• Cylindrical shank at 0.1615 inches for direct collet or chuck mounting
• 1.581-inch flute length provides adequate chip clearance in the bore

Compatibility

Designed as an OEM-style precision tooling replacement for combo drill reamer applications requiring a 0.1615-inch finished bore diameter with a cylindrical shank and standard collet mounting.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians familiar with small-diameter carbide tooling. Ensure the spindle and collet system are clean and properly torqued before seating the cylindrical shank. Carbide tooling is brittle — avoid side loading, interrupted cuts beyond the tool's rated use, or dropping the tool on hard surfaces. Verify spindle speed and feed rate against the tooling manufacturer's recommendations for the specific workpiece material before cutting.
