Precision cutting and low effort: precision-ground cutting surfaces and 6 flutes reduce friction and make reaming easier and smoother, so you can enlarge or finish tapered holes with less force and cleaner results. Durable hardened steel construction: made from 45# steel, a hardened tool steel chosen for strength and resistance to breakage during hand use. Two convenient sizes: set includes 2 taper reamers with T-handle for Ø 3-13mm and Ø 5-16mm to cover common tapered hole ranges. Removable T-handle for control and storage: the T-shaped handle detaches for compact storage and transport; when attached it provides better rotation and secure hand control for precise reaming. Designed for pin holes: each hand reamer features the correct taper and a pin hole (stegstiftloch) so it is suitable for preparing or adjusting bridge pin or end pin holes. Key attributes Function: chamfering and reaming of tapered holes with controlled material removal. Compatibility: specifically suitable for bridge pins and end pins; also useful for tapered dowels and general tapered hole tasks. Material: 45# hardened tool steel for long life and reliable performance. Performance: 6 flutes for efficient chip removal, smooth rotation, and accurate sizing. Typical applications Guitar maintenance and building: prepare or ream bridge pin holes and end pin holes for a precise fit without splitting or tearing the wood. General woodworking: create or refine tapered holes for dowels, pegs, or fittings where a controlled taper is required. Workshop repairs: resize or clean out worn or slightly oversized tapered holes in furniture or small assemblies. What you get Two T-handle taper reamers: Ø 3-13mm and Ø 5-16mm, each with removable T-handle and pin hole for secure alignment. A durable hand tool set intended for repeatable, accurate tapered-hole work in wood and similar materials. Use tips Attach the T-handle for best control during reaming, then remove for compact storage. Work slowly and check fit frequently to avoid removing too much material. Keep blades clean of resin and debris to maintain cutting performance.
