What this tool solves Quickly and precisely tapers and refines round holes in wood so pins, dowels, or fittings seat correctly and smoothly. Provides better control and leverage to reduce slipping and improve hole symmetry compared with ordinary hand files. Key features and benefits Conical reamer with T-handle: T-handle plus included control grips give extra leverage and steady handling for accurate, round holes. Six grooves (ridges): The six flutes help cut and remove material evenly for a consistent taper. Hardened carbon steel construction: Made from hardened carbon steel with ground cutting edges for durable performance and reliable edge retention. Wide size range: Tapers holes from 5 mm to 16 mm, suitable for finishing holes for retaining pins, end pins, dowels, and other small fittings. How it performs Controlled hand operation lets you open or refine a hole gradually until the required diameter and fit are achieved. Durable steel edges keep cutting action effective over repeated use in wood. Typical applications Furniture repair and assembly: Taper holes for end pins, dowels, or pegs so joints fit tightly and align properly. Sink and countertop work in wood: Refine or enlarge holes for fixtures or fittings in wooden countertops and wooden sink surrounds. Custom woodworking and cabinetry: Create chamfers, reversed cones, or neat tapered openings for fittings, trim pins, or decorative work. Practical details Size range: 5–16 mm taper. Material: Hardened carbon steel with ground cutting edges. Includes: Conical reamer with T-handle and control grips for steady operation.
