OKODOKO Handheld Tapered Reamers - 3-13mm & 5-16mm - 1/4 Inch Hex Shank

Tapered reamers are primarily used to enlarge existing holes, create precisely tapered holes, chamfer edges, countersink screws, and remove burrs from materials like wood, plastic, and soft metals.

Yes, the 1/4 inch universal hex shank is designed to fit in the chuck of most standard power drills and drill presses.

The reamers cover both metric (3-13mm) and imperial (5-16mm) ranges, meaning they can accurately work with holes measured in millimeters or inches within these specified ranges.

For manual control, using the T-handle provides a secure grip and leverage. When using a power drill, start at a low speed and apply steady, consistent pressure, using the drill's depth control if available.

While the wear-resistant steel construction offers durability, these reamers are best suited for wood, plastic, and softer metals. Performance on very hard metals may be limited.

After use, clean the reamer with a brush or cloth to remove debris. Store in a dry environment to prevent rust. Inspect cutting edges periodically.

These reamers create clean, round, and precisely tapered holes. They are designed to smooth and enlarge existing holes to a specific taper.

Ensure the reamer is properly seated in the drill chuck or T-handle. Check if the cutting edges are dull; sharpening may be required. Verify you are using the correct speed and pressure for the material.

Practice with manual feed rate control when using a power drill. For manual use, ensure a steady, even rotation with the T-handle. Verify the reamer is centered correctly on the pilot hole.

Ensure the reamer shank is fully and securely gripped by the drill chuck. If using a T-handle, ensure it is securely attached. Try a lower drill speed.

Apply steady, even pressure. If using a power drill, consider backing the reamer out slightly and re-engaging to clear material. Ensure pilot hole is sized appropriately for the reamer.
