Bullet Points

Tungsten Carbide Construction: Made from premium solid carbide (tungsten steel), offering hardness up to HRC 60+ workpiece capability, superior wear resistance and 3–5x longer tool life than HSS reamers.

Precision to IT6 Tolerance: Engineered for ultra-precise hole finishing, achieving IT6–IT7 dimensional tolerance and Ra 0.8–1.6μm surface finish, eliminating the need for secondary honing operations.

Morse Taper Shank for Maximum Rigidity: MT1–MT4 taper shank design provides superior grip, self-centering alignment, and vibration dampening compared to straight shank reamers, ensuring consistent concentricity.

Customized Cutting Geometry: Tailor-made cutting angles designed per workpiece material — hardened steel, steel, cast iron, aluminum, non-ferrous alloys — optimizing chip formation and edge wear for each specific application.

Hot Q&A

What materials can this carbide taper shank reamer be used on?

Answer: The solid carbide model is suitable for hardened steel up to HRC 60+, stainless steel, heat-resistant alloys, carbon steel, alloy steel, cast iron, aluminum, and non-ferrous metals. Thanks to the tungsten carbide construction, it performs exceptionally well in abrasive and hard-to-machine materials where HSS tools wear out quickly. Please specify your workpiece material when ordering so we can recommend the optimal grade, coating, and cutting geometry.

How does the Morse Taper shank improve performance compared to a straight shank?

Answer: The Morse Taper shank provides a self-locking tapered fit that offers superior grip, better alignment, and reduced vibration compared to straight shanks. This results in higher concentricity, tighter hole tolerances, and the ability to handle higher torque loads — especially important for larger diameter reamers and harder materials.

What tolerance and surface finish can I expect?

Answer: Our reamers are manufactured to achieve IT6–IT7 dimensional tolerance per ISO standards, with surface finish of Ra 0.8–1.6μm under proper machining conditions. The actual result depends on the pre-reamed hole quality, cutting parameters, coolant usage, and machine condition. We recommend a reaming allowance of 0.10–0.30mm on diameter.

Can I order custom sizes and specifications?

Answer: Yes, we offer full OEM/ODM customization. You can specify the reaming diameter, tolerance class, flute type (straight or helical), shank taper size (MT1–MT4), coating type, and overall length. When ordering, please provide the hole diameter tolerance, surface finish requirement, and workpiece material so our engineering team can design the optimal tool geometry for your application.
