Product Overview

Our solid carbide straight-flute drill reamer is specially designed for precision drilling and reaming operations in soft, non-ferrous materials such as aluminum, copper, brass, and non-metallic composites. Combining drilling and reaming in a single step, this tool improves machining efficiency while delivering high concentricity, tight tolerances, and excellent surface finish.

Manufactured from ultra-fine grain tungsten carbide, the reamer offers excellent rigidity, wear resistance, and dimensional stability — making it ideal for high-speed CNC machining of soft metal parts requiring clean, burr-free holes.

Key Features

• Material-Specific Design: Optimized geometry for aluminum, copper, and brass

• Straight Flute Geometry: Prevents chip jamming and ensures smooth hole walls

• One-Step Drill & Ream: Increases machining speed and reduces tool changes

• Tungsten Carbide Construction: High hardness, low wear, long tool life

• Tight Tolerances: Achieves precision up to ±0.005 mm

• Excellent Surface Finish: Delivers Ra 0.6–1.0 μm depending on material and setup

Applications

• Machining of aluminum alloy components for automotive, aerospace, and electronics

• Copper/brass connector housings, heat sinks, and terminal blocks

• Soft metal precision parts with high hole quality requirements

• Ideal for high-speed CNC machining centers, automated production lines, and multi-axis machines

Technical Specifications (Customizable)

Advantages

• Combines drilling and reaming in a single operation

• Reduces machining time and tool inventory

• Straight flute avoids chip clogging in soft, ductile materials

• Maintains excellent roundness and hole consistency

• Supports high spindle speeds and coolant-through options

Usage Recommendations

• Use with low-viscosity cutting fluid for aluminum or air blast to aid chip evacuation.

• Ideal for through-holes; for blind holes, ensure proper chip clearance.

• Run at high spindle speeds with moderate feed to optimize finish and accuracy.

• Store in dry, dust-free conditions to protect sharp edges.
