Description: ISO 30 ER32 Tool Holder ISO 30 taper50mm (1.96 inch) length .00016" or 4 micron precision HRC 58-62 20CrTiMn Stainless alloy Balanced at G2.5 30,000 RPM standards (might be marked GM2.5)Balanced Nut ER32 collet sizeUniform Electroless Nickel Plating .005mm or .0002" (prevents rust) Includes HSD style Pull Stud Material 20CrMnTi stainless alloy is ideal for obtaining material stability, resist corrosion and to achieve the desired hardness of RC 58-60. Mn (Manganese) and Ti (Titanium) are essential elements needed to stabilize the grain structure of the steel. Without these elements the steel grain structure can crack, move and warp over time with terrible consequences to the runout or stability. Additionally Cr (Chromium) is added to help in resisting corrosion. Lastly the material is case hardened to 56-60 HRC to match the hardness on the mating surfaces of the spindle. If these hardnesses are not matched the holder and or spindle can have premature wear. With case hardening the center of the holder stays softer around 30 HRC to handle the repeated clamping forces changing tools without cracking. Electroless Nickel Plating This tool holder features nickel plating to prevent rust and prevent wear. Unfortunately the perfect alloys for tool holders are not rust free. Every alloy used by top brands will rust. To go a step above, this tool holder has a uniform nickel plating that will resist corrosion while keeping a tight runout. Nickel plating is also tough and will prevent wear causing this holder to keeps it's precision longer with repeated use. Precision and Balance Balancing helps with vibration which prevents premature bearing failures in the spindle. Balancing was performed on a Haimer machine to meet the G2.5 specification for 30K rpm. Precision decreases runout which causes chip thickness to vary over the tool rotation and therefore the tool experiences uneven forces during each cutting flute period. This will force a reduction in feedrate and tool life because one flute is doing more work. Shipping is Fast and Additional items ship FREE!
