🔹 KEY FEATURES 

• Wide Adjustable Size Range (H1–H10):
  Covers hole diameters from 3/8″ to 15/16″, offering excellent flexibility for multiple reaming, finishing, and fitting applications without the need for multiple fixed-size reamers.

• High-Quality Carbon Steel Blades:
  Precision-ground carbon steel cutting edges provide sharp, clean cuts, excellent wear resistance, and consistent performance even in demanding workshop environments.

• Strong Mild Steel Body Construction:
  The durable body ensures rigidity, stability, and long-term reliability while maintaining accurate blade alignment during adjustment and operation.

• Precision Hole Finishing & Sizing:
  Ideal for final sizing, hole correction, bore truing, and smooth internal finishing, ensuring accurate fits for shafts, pins, bushes, and mechanical assemblies.

• Straight Flute Design for Stability:
  Straight flutes reduce vibration and chatter, improve cutting control, and deliver cleaner surface finishes compared to aggressive spiral designs.

• Multi-Material Compatibility:
  Suitable for use on steel, aluminum, brass, copper, wood, plastic, and soft alloys, making it a versatile tool for metalworking and woodworking tasks.

• Hand Reamer Design for Controlled Cutting:
  Designed for manual use, allowing precise pressure control, improved accuracy, and reduced risk of oversizing compared to powered reaming.

• Ideal for Professional & DIY Use:
  Perfect for machinists, engineers, automotive technicians, toolmakers, maintenance professionals, and hobbyists requiring reliable precision tools.
