Reamer FANAR DIN 335-C 90° × 25.0 mm HSS TiN

The FANAR reamer DIN 335-C 90° × 25.0 mm HSS TiN is a solid high-speed steel tool designed for precision enlargement and finishing of drilled holes. Manufactured to DIN 335-C geometry with a 90° chamfer/point and a nominal diameter of 25.0 mm, the reamer provides controlled material cutting for accurate hole sizing and smooth internal surfaces. A titanium nitride (TiN) coating increases wear resistance and reduces friction, extending tool life in general workshop and industrial reaming operations on steel and other common machinable materials.

Advantages

The solid HSS construction delivers toughness and edge retention required for reliable finishing operations. The TiN coating improves surface hardness and reduces built-up edge, helping to maintain dimensional accuracy over longer production runs. DIN 335-C geometry with a 90° point promotes stable entry into holes and consistent cutting action, while the 25.0 mm nominal diameter matches standard hole-sizing tolerances for straightforward integration into drilling and reaming workflows.

Suitable for

• Precision reaming of drilled holes in steel and general machinable metals
• Finishing operations to achieve accurate diameters and smooth internal surfaces
• Workshop and light industrial machining where consistent hole tolerances are required
• Use in dedicated reaming setups or following drilling operations

Key specifications

• Tool type: solid reamer, HSS (high-speed steel)
• Geometry standard: DIN 335-C with 90° point/chamfer
• Nominal diameter: 25.0 mm
• Surface treatment: TiN (titanium nitride) coating for increased wear resistance
• Intended materials: steel and common machinable metals

How to use

Select a drill size slightly undersized relative to the target diameter according to standard reaming practice, clamp the workpiece securely, and ensure the reamer is run at appropriate spindle speed and feed for HSS tools and the material being machined. Use cutting fluid suitable for ferrous materials to improve finish and tool life. Feed the reamer steadily without reversing while engaged in the cut; withdraw the reamer only after the spindle has stopped rotating or at an appropriate slow retract speed to avoid damaging the cutting edges.

Usage recommendations

For best results, match spindle speed and feed to material hardness and machine rigidity, maintain correct runout and alignment, and use moderate cutting fluid application. Inspect the reamer regularly for wear and replace when dimensional accuracy or surface finish degrades.
