ENGINEERED SOLID CARBIDE REAMERS
Solid Carbide Reamers for Precision Hole Finishing
Standard and custom solid carbide reamers for straight-flute, spiral-flute, blind-hole and through-hole applications—developed around the required diameter, tolerance and production conditions.
The nominal diameter is only the starting point. We configure the reamer around the actual hole and production conditions.
Hole size or finish driftsWe set the reaming allowance, cutting geometry and edge preparation around the material, pre-hole and target tolerance.
Chips damage the finished boreWe configure flute direction and coolant delivery to move chips away from the cutting and finished surfaces.
A catalogue reamer does not fit the componentWe develop the diameter, guide, step and coolant features from your drawing and confirm them before grinding.- Workpiece material

Features of the solid carbide reamer
Excellent reaming performance.
Made from high-purity tungsten carbide (WC-Co) fine-grain material for superior durability.
Efficiently processes difficult-to-machine materials such as titanium alloys, Inconel, and HRC45-60 hardened steels.
Suitable for machining common materials like cast iron, aluminum alloys, and stainless steel.
Precision-ground cutting edges with optimized flute design ensure H5-H7 tolerance control and low surface roughness.
No burrs or residue left, even in high-speed or intermittent cutting applications.
Stable performance under high cutting speeds, meeting batch production requirements.
Strong consistency in machining quality, reducing tool changes and improving production efficiency.
Coatings enhance durability.
Multiple high-performance coating options to precisely match different machining scenarios:
TiAlN coating (high temperature, oxidation resistance) for high-speed cutting of steels and alloys.
DLC coating (low friction, wear resistance) for machining non-ferrous metals and sticky materials.
AlTiN coating (high hardness, corrosion resistance) for extreme machining conditions.
Coatings form a protective barrier on the tool surface, significantly reducing cutting friction.
Coated tools offer 3-5 times longer lifespan compared to uncoated reamers, ensuring stable performance during long-term, continuous operations.
Sundi, in partnership with Oerlikon, uses the most advanced and precise coating technologies available to recommend the best coating solution for your machining conditions.

FAQ
The main purpose of a reamer is to provide precision finishing to an existing hole, improving its size, shape, and surface finish. Reamers are typically used to achieve tight tolerances and smooth surfaces, ensuring that holes are accurate and consistent.
The three types of reamers are:
Solid Reamer: Made from a single piece of material (usually high-speed steel or carbide), solid reamers are used for general precision hole finishing. They offer durability and high precision but are best suited for softer materials.
Carbide-Tipped Reamer: These reamers feature carbide tips brazed onto the cutting edges, providing enhanced hardness and wear resistance. They are ideal for machining harder materials, such as steel, and offer longer tool life and superior cutting performance.
Inserted Blade Reamers: Inserted blade reamers use replaceable carbide or other hard material inserts for cutting. These reamers are designed for high-volume or heavy-duty operations, as the inserts can be replaced when worn out, extending tool life and reducing downtime.
While a drill bit can be used to create a hole, it is not designed to achieve the high level of precision that a reamer provides. A drill bit will leave a rougher surface and may not achieve the tight tolerances that a reamer can. For precise hole finishing, a reamer is preferred.
