  • Solid Carbide Taper Shank Spiral Flute Reamer H7 Morse Taper Precision Reaming Tool CNC

    Solid Carbide Taper Shank Spiral Flute Reamer H7 Morse Taper Precision Reaming Tool CNC

    The Carbide Taper Shank Spiral Flute Reamer is a precision hole-finishing tool engineered for high-accuracy reaming of steel, cast iron, and non-ferrous metals such as aluminum and brass. Made from solid carbide (tungsten carbide), it combines a Morse taper shank (No.1–No.4) with an optimized spiral flute geometry to deliver stable, smooth, and consistent hole quality in CNC machining centers, drill presses, lathes, and other machine tools.

  • Solid Carbide Internal-Coolant Machine Reamer H7 CNC Precision Reamer Steel Aluminum Alloys

    Solid Carbide Internal-Coolant Machine Reamer H7 CNC Precision Reamer Steel Aluminum Alloys

    OPT internal-coolant solid carbide machine reamers are manufactured from ultrafine-grain tungsten carbide with through-coolant channels delivering coolant directly to the cutting edges. Engineered for semi-finishing and finishing of high-precision holes, the internal coolant design provides powerful chip evacuation and heat control when machining soft steels, stainless steel, titanium and other chip-adhesive materials, delivering superior bore surface quality and extended tool life on CNC machining centers, lathes and automated production lines.

  • Solid Carbide Spiral Flute Machine Reamer H7 CNC Reamer TiAlN Coated for Steels & Cast Iron

    Solid Carbide Spiral Flute Machine Reamer H7 CNC Reamer TiAlN Coated for Steels & Cast Iron

    This Spiral Flute Solid Carbide Machine Reamer is a precision reaming tool engineered for high-accuracy hole finishing on CNC machining centers, drilling machines and lathes.

    Made from micro-grain solid carbide (tungsten steel) with ISO K10/K20 grade substrate, it delivers stable H7-class hole tolerance, excellent surface finish and long service life when reaming steel, cast iron, aluminum alloys and other metals.

  • Solid Carbide Long Machine Reamer H7 Tungsten Carbide Reamer For Deep Hole CNC Machining

    Solid Carbide Long Machine Reamer H7 Tungsten Carbide Reamer For Deep Hole CNC Machining

    The Long Machine Reamer is a high-precision carbide reaming tool engineered to enlarge and finish pre-drilled holes with exceptional accuracy. Manufactured from premium tungsten carbide (solid carbide) or carbide-tipped alloy steel, it delivers superior wear resistance, consistent H7/H8 tolerance, and smooth surface finish (Ra ≤ 1.6 µm) for demanding deep-hole and mass-production machining applications.

  • Replaceable Head Carbide Reamer H7 Tungsten Carbide Modular High Precision Reaming Tool CNC

    Replaceable Head Carbide Reamer H7 Tungsten Carbide Modular High Precision Reaming Tool CNC

    The Replaceable Head Carbide Reamer is a modular precision cutting tool designed for enlarging and finishing pre-drilled holes to H7 tolerance (±0.01 mm). Its standout feature is the interchangeable tungsten carbide cutting head: when the head wears out, only the head is replaced while the durable shank is reused, cutting long-term tool cost and reducing waste.

  • Straight Flute Tungsten Steel CNC Machine Reamer for Automotive Aerospace Mold Making

    Straight Flute Tungsten Steel CNC Machine Reamer for Automotive Aerospace Mold Making

    This machine reamer is a high-precision cutting tool designed to refine and enlarge pre-drilled holes to exact dimensions, delivering smooth finishes and tight tolerances. Manufactured with a solid carbide tungsten steel body, it efficiently machines steel, cast iron, non-ferrous metals and composites, and is compatible with CNC machining centers, drill presses and lathes for automotive, aerospace and mold-making applications.

  • Solid Carbide Taper Shank Machine Reamer Morse Taper Reamer for Metal Hole Finishing

    Solid Carbide Taper Shank Machine Reamer Morse Taper Reamer for Metal Hole Finishing

    The Taper Shank Machine Reamer is a precision cutting tool engineered for high-accuracy hole finishing in metal machining operations.Designed to deliver tight dimensional tolerances (IT6–IT7) and excellent surface finish (Ra 0.8–1.6μm), it is the ideal solution for finishing pre-drilled or bored holes to exact specifications across a wide range of industrial applications.

  • TE Indexable U Drill Internal Coolant SPMT SPGT XOMT Insert Drill CNC Metal Hole Opener

    TE Indexable U Drill Internal Coolant SPMT SPGT XOMT Insert Drill CNC Metal Hole Opener

    OPT TE Indexable U Drill is a high-efficiency CNC drilling tool designed for fast, accurate, and cost-effective hole-making in metal workpieces. It accepts industry-standard SPMT, SPGT, and XOMT indexable inserts, allowing users to replace only the cutting edge instead of the whole tool. The internal coolant design delivers coolant directly to the cutting zone, improving chip evacuation, reducing heat buildup, and extending tool life.

  • High Precision No Bottom Hole Straight Flute Thread Mill Carbide Thread Milling Tool

    High Precision No Bottom Hole Straight Flute Thread Mill Carbide Thread Milling Tool

    straight flute thread mill is specially engineered for high-precision threading on stainless steel materials. Made of ultra-hard submicron solid carbide, matched with TiAlN high friction-resistant coating, it bears high cutting force and high temperature generated during stainless steel processing.
