HSS M35 MACHINE REAMER - METRIC (1 PC) #H39 | CTC Tools

Notes on Use Appropriately reducing the cutting speed and feed speed can prolong the service life of the reamer; Provide smoother chip removal and easy to process high-quality workpieces. High speed steel Made of High-speed steel, HSS has high hardness, high wear resistance and high heat resistance to ensure processing efficiency. Explanation of Reaming Allowance In order to improve its dimensional accuracy and hole surface quality, reasonable reaming can effectively improve the hole accuracy and surface quality. Generally, the reaming allowance is 0.1-0.25mm (one side). For larger diameter holes, the reaming allowance should be increased appropriately, but the allowance should not be greater than 0.3mm. There is an experience that suggests to reserve a thickness of 1-3% of the reamer diameter as the reaming allowance (diameter value). For example, it is more appropriate to add a Φ20 reamer with a hole diameter of about Φ19.6: 20－(20×2/ 100)=19.6 【MATERIAL】Made by high speed steel, combination of hardness and toughness for wear resistance. 【FEATURE】: Designed for reaming to mold processing and handicraft processing. Allows chips to collect in the flutes when cutting, suited for most applications in shallow cuts.
