Reamers – Precision Hole Finishing Tools by Snijer

Reamers – Precision Hole Finishing Tools

At Snijer, we manufacture high-precision reamers engineered to achieve exact hole diameters, superior surface finish, and perfect roundness. Reamers are essential finishing tools used after drilling or boring operations to bring holes to tight tolerances and ensure accurate fits for shafts, pins, bearings, and assemblies.

Our reamers are designed for stability, long tool life, and consistent results in both CNC and conventional machining applications.

Types of Reamers and Their Applications

  * Hand Reamers
Used for manual finishing operations where fine control is required. Hand reamers are ideal for low-volume work, maintenance, and repair tasks, allowing precise adjustment and smooth hole finishing.

  * Machine Reamers
Designed for use on CNC machines, lathes, and milling machines. Machine reamers ensure high repeatability, consistent hole size, and efficient production in serial manufacturing.

  * Solid Carbide Reamers
Ideal for high-speed machining and abrasive materials. Solid carbide reamers provide excellent wear resistance, longer tool life, and superior surface quality, especially in hardened steels and high-alloy materials.

  * HSS (High-Speed Steel) Reamers
Versatile and cost-effective, suitable for a wide range of materials including steel, aluminum, and cast iron. HSS reamers offer good toughness and flexibility for general-purpose applications.

  * Shell Reamers
Designed for large-diameter holes, shell reamers are mounted on an arbor and used primarily in heavy-duty and industrial applications. They allow cost-efficient replacement of cutting bodies without changing the entire tool, making them ideal for high-volume production and large-scale machining.

  * Adjustable Reamers
Equipped with adjustable blades, these reamers allow fine diameter adjustments. They are commonly used for maintenance, repair, and applications where hole sizes may vary slightly.

  * Expansion Reamers
Used when slight wear compensation is needed. Expansion reamers can be adjusted minimally to restore accuracy over extended tool life.

  * Taper Reamers
Designed to produce or finish tapered holes. Commonly used for Morse tapers, pin fittings, and alignment applications where precise angular accuracy is required.

  * Chuck Reamers
A straight or spiral flute reamer designed specifically for machine use with high accuracy. Frequently used in precision machining and mass production environments.

  * Custom Reamers
Engineered according to customer drawings and specifications. Custom reamers are ideal for special materials, complex geometries, tight tolerances, or unique production requirements.
