Hand reamer for metal and woodworking, designed to enlarge and finish holes accurately. A tool that helps avoid sloppy fits when repairing pipework, fittings or making precise holes. Is the sourcing map Adjustable Hand Reamer the right addition to your workshop kit?
⚡ At a Glance
- • Cutting Quality: Adjustable finishing with H8 accuracy and six straight flutes for controlled, repeatable cuts
- • Best for: Workshop repairs, metalworkers and hobbyists needing precise hole sizing between 11.75mm and 12.75mm
- • Not ideal for: High-volume industrial reaming or machining of hardened steels where specialised machine reamers are required
Adjustable range covers 11.75–12.75mm cutting diameter with H8 tolerance and six straight flutes. Constructed from high-speed steel with a 45mm flute length, 6.1mm square shank and 136mm overall length.
Precise hole sizing - with adjustable 11.75–12.75mm cutting range
An internal adjustment mechanism allows fine changes to the cutting diameter within the stated range, while H8 accuracy defines the finished tolerance level. The metric scale and locking arrangement enable controlled, light cuts during reaming.
Achieve repeatable diameters for tight-fitting parts and repair work, cutting down on trial-and-error and rework.
Durable cutting life - with high-speed steel H8 construction
High-speed steel substrate gives a balance of hardness and toughness, resisting wear and withstanding higher temperatures than ordinary carbon steels. The uncoated finish accepts cutting fluid to help reduce friction and preserve edge sharpness.
Sharp edges last through multiple light reaming tasks, making the tool suitable for regular workshop use without frequent replacement.
Cleaner chips and controlled hand operation - with six straight flutes
Straight flutes help chips and debris exit the bore predictably and suit shallow cutting depths common in hand reaming. Compatibility with wrenches, T-handles, extension rods or drill chucks allows matched torque and speed for the job.
Easier chip evacuation and steadier cutting when working by hand reduce chatter and the chance of oversized holes.
