Adjustable Hand Reamers
AIMS Industrial stocks adjustable hand reamers for finishing bored or drilled holes to precise dimensions in toolrooms, workshops and maintenance environments. With expandable blades covering a range of diameters from a single tool, our range from Maxigear, Sutton Tools and Bordo suits both metric and imperial bore finishing requirements.
Features of Adjustable Hand Reamers
- Adjustable blade range: Each reamer covers a diameter range (e.g. 11.1–12.7 mm) — one tool handles multiple close-tolerance bore sizes, reducing tooling inventory.
- Left-hand helix flutes: Opposite-hand flutes lift chips away from the cutting edge during forward rotation, preventing chip re-cutting and bore damage.
- HSS cutting blades: High-speed steel blades maintain cutting edge integrity across a wide range of materials including cast iron, steel and aluminium.
- Taper shank: Square drive end for use with a tap wrench — provides manual feed control for precise hole size creep and optimal surface finish.
- Reamer tolerances: Quality reamers hold H7 bore tolerances when correctly aligned and fed — critical for bearing, bush and pin fit applications.
Application and Usage Tips
- Bore allowance: Leave 0.1–0.3 mm of material for reaming — too much stock risks blade deflection and bell-mouthing; too little leaves insufficient material to size.
- Cutting fluid: Always use cutting oil with hand reamers in steel — dry reaming accelerates blade wear and produces a poor surface finish.
- Feed rate: Apply steady, constant downward pressure during forward rotation — never rotate backwards, as this dulls cutting edges rapidly.
- Blade adjustment: Adjust blades evenly around the periphery to maintain concentricity — uneven adjustment causes bore taper and poor finish.
