Solid Carbide Hand Reamer Precision H7 Reaming Tool Straight Flute for Mold Automotive Aerospace

Short Description:

solid carbide hand reamer is a precision cutting tool designed to enlarge and finish pre-drilled holes to an exact diameter with excellent roundness, straightness and surface quality. Manufactured from 100% solid sintered tungsten carbide, it delivers far higher hardness, rigidity and wear resistance than HSS reamers, keeping cutting edges sharp over long production runs. Each reamer is 100% inspected through three-stage quality control before shipment.

Material: Solid sintered tungsten carbide
Hardness: 88.5–92.5 HRA
Tolerance Grade: H7

Bullet Points

Superior Wear Resistance: Wear resistance roughly 5–10x that of HSS keeps edges sharp and hole size stable in mass production.
High Machining Precision: H7 standard tolerance (H6 available on request), hole accuracy within ±0.01 mm with excellent roundness.
Extended Tool Life: Tool life 3–5x longer than HSS reamers, cutting downtime and cost per part.
Mirror-Grade Surface Finish: Bored hole surface Ra ≤ 0.2 μm; honing/polishing is often eliminated.
Full Customization: OEM/ODM for non-standard diameters, stepped/tapered bores, special flutes, internal coolant and coatings.
