The causes and countermeasures for these issues are provided. Please make use of them. 【Contents (excerpt)】 <Troubles> ■ Poor surface finish ■ Enlargement or reduction of hole diameter ■ Cylindricity and roundness defects ■ Short tool life ■ Occurrence of reamer breakage or seizing *For more details, please refer to the PDF document or feel free to contact us.

Here is an introduction to the differences between reamers and drills. First, regarding "machined hole dimensions and surface roughness," for a carbide reamer with a diameter of φ6.0, the machined hole dimensions are φ5.998 to 6.000mm (10 holes), which provides a good fit. In the case of a carbide-coated drill with a diameter of φ6.0mm, the machined hole dimensions are φ5.980 to 6.000mm (10 holes). We also provide comparative data on "roundness and cylindricity." Detailed explanations with diagrams are available in the PDF. Please download it for your reference. 【Machined Hole Dimensions and Surface Roughness】 ■ Carbide Reamer φ6.0 - Machined hole dimensions: φ5.998 to 6.000mm (10 holes) - Hole diameter difference: 2μm, surface roughness: Rz1.6μm ■ Carbide-Coated Drill φ6.0mm - Machined hole dimensions: φ5.980 to 6.000mm (10 holes) - Hole diameter difference: 20μm, surface roughness: Rz6.2μm *For more details, please refer to the PDF document or feel free to contact us.

We will introduce the impact of the accuracy of the pilot hole on the precision of reaming. In the case of drills, the cylindricity is 52.7μm, while for high-speed steel reamers, it is 18.5μm. High-speed steel reamers are more susceptible to the influence of pilot hole accuracy. With the carbide reamer G series, the impact of pilot hole accuracy is minimized, resulting in high precision finishing. Please download the PDF for a detailed explanation with diagrams. 【Carbide Reamer G Series [Model: CG] Specifications (Excerpt)】 ■ Material to be machined: S50C ■ Machining hole depth: 18mm (through) ■ Reamer diameter: φ6.0 ■ Reamer allowance: φ0.2 ■ Projection: 42mm *For more details, please refer to the PDF document or feel free to contact us.

For high-speed steel reamers, we have the "HGF.P. Gold Reamer" and "HB Short Reamer" among our lineup. You can choose from a variety of options to suit different applications. 【Carbide Reamer Lineup (Excerpt)】 ■ CR-H Carbide Reamer R Series ■ CR Carbide Reamer R Series ■ CE-H Carbide Reamer E Series ■ CE Carbide Reamer E Series ■ CM Carbide Reamer μ Reamer *For more details, please refer to the PDF document or feel free to contact us.

• Reamer

We will introduce a machining case using ultra-hard carbide reamer (work material S50C). Tool wear is minimized as cutting speed increases, extending tool life. The measurement results of roundness and cylindricity of the machined holes (average after machining 400 holes) showed that increasing the cutting speed resulted in better hole accuracy. Detailed explanations with diagrams are provided in the PDF. Please download and utilize it. 【Specifications (excerpt)】 ■ Work material: S50C t=18mm ■ Machined hole depth: 18mm (through) ■ Reamer diameter: φ6.0 ■ Pilot drill: carbide drill φ5.8 ■ Reamer allowance: φ0.2 *For more details, please refer to the PDF document or feel free to contact us.

●High-precision machining compatible 　Blade diameter tolerance ΦD = 0 to +0.005 mm ●Complete blind hole machining possible 　An end cutter is added to the reamer mechanism. Complete blind hole machining is possible. Due to the right lead, chip discharge is smooth. Chips are discharged upward, preventing accumulation at the bottom. ●Newly developed special coating 　Coating hardness approximately 3,000 Hv. Machining of difficult materials ranging from mold tool steel to Inconel and Hastelloy, with hardness between 20 to 50 HRC, is possible. Due to the low friction coefficient, chip discharge is smooth in conjunction with the right lead shape. It also excels in heat resistance, demonstrating its effectiveness under the harsh conditions of blind holes. ●Adoption of end mill shank
