ER32 Collet Chuck Holder — Speed Steel Milling Shank for CNC Lathe A precision ER32 collet chuck holder made from Speed Steel (HSS) with a Morse taper shank and a 1–20 mm clamping range. Designed for secure, concentric clamping of round shanks and tooling in drilling machines, milling machines, lathes, table drills, and CNC lathes. Key benefits Secure clamping: ER32 system provides reliable grip across a wide range of tool diameters (1–20 mm), reducing slippage during cuts and drills. Versatile compatibility: Morse taper shank fits spindles that accept Morse taper tooling and the ER32 collet accepts standard ER32 collets for flexible tool changes. Durable material: Speed Steel construction improves wear resistance and supports speed machining operations. Improved accuracy: Tight concentric clamping minimizes runout and vibration, improving hole quality and surface finish while extending tool life. One tool for many machines: Use the same holder across drilling machines, milling machines, lathes, table drills, and CNC lathes to simplify tooling needs. Key attributes Collet specification: ER32 collet chuck system. Clamping range: 1–20 mm (accepts ER32 collets covering this range). Shank type: Morse taper shank for secure spindle fitting. Material: Speed Steel (HSS) body and shank. Applications: Suitable for drilling, milling, turning, reaming, tapping, and other rotary tool operations in compatible machines. Use cases Precision holemaking on a CNC lathe: Hold smalldiameter drills or reamers with minimal runout for accurate axial holes and tight tolerances during livetool operations. Milling small features on a milling machine or table drill: Mount end mills, drills, or rotary tools in the ER32 collet to machine pockets, contours, and fine features with consistent clamping across multiple tool sizes. Lathe accessory for secondary operations: Securely hold drills or reamers when performing drilling or finishing passes on a lathe, allowing a single setup to complete both turning and drilling tasks. Practical notes Compatibility requires a spindle or adapter that accepts the specified Morse taper shank; ensure your machine's taper matches before installation. Use standard ER32 collets sized to the tool shank diameter for clamping performance within the 1–20 mm range. Inspect collet and holder surfaces for cleanliness and wear before each use to maintain concentricity and safe operation. This ER32 Collet Chuck Holder offers a simple, durable solution for users who need a single, accurate holder across multiple machines. Its HSS construction, Morse taper shank, and 1–20 mm ER32 clamping range make it a practical choice for precision drilling and milling tasks on CNC lathes, milling machines, lathes, drilling machines, and table drills.
