Tapered Hand Reamers 1:50 5mm Small Dia 6.2mm Big Dia High Speed Steel (HSS) Slope Pin Reamer for Tapered Pin Hole Mould Machining DRINYOUNG (5mm-6.2mm)

["Size - 1:50 taper reamer; cutting diameter: 5mm / 0.2\" (small), 6.2mm / 0.24\" (big);tool flute length: 60mm / 2.36\";overall length:85mm / 3.35\".","Design – 1:50 taper, suitable for machining applications that require precise tapered fits, such as locating pin holes.","Material – Manufactured from high-speed steel (HSS), offering excellent wear tolerance and stable cutting performance.","Process Characteristics – Optimised flute geometry and keen cutting edges ensure smooth debris evacuation and efficient cutting action, helping to produce dimensionally accurate tapered holes featuring a clean surface finish.","Application Methods – Can be used with machine tools such as drilling and milling machines; experienced operators may also use it for manual operations.","Usage Tip – Friction heat is generated during hole expansion. Using appropriate lubricants reduces friction, increases the reaming speed, and extends tool longevity."]
