LÖSNING Collet Block (Square / Hex) — ER32 / ER40

Genuine LÖSNING square and hex collet blocks for ER32 and ER40 collets, stocked by San Tools in the UAE. These precision-ground blocks hold a workpiece square (90°) or on the six flats (60°/hex) via a standard ER collet, letting you index a part accurately on a surface grinder, mill, or bench vice without re-setting.

Features

• Square & Hex Options — indexes work on 90° faces (Square) or 60° flats (Hex) from the same ER collet
• ER32 & ER40 Compatible — takes standard ER32 or ER40 collets for a wide clamping range on each block
• Precision Ground Faces — flat, square-to-bore reference faces for accurate indexing and repeatable set-ups
• Hardened Body — wear-resistant construction holds accuracy through repeated clamping and grinding use
• Bench & Grinder Ready — sits flat on a magnetic chuck or vice jaw for grinding, inspection, or light milling work

How to Use

• Match Collet Size — select the ER32 or ER40 block to suit the collets already in your set
• Fit the Collet & Part — insert the correct ER collet for your workpiece diameter, then load the part
• Seat the Block Flat — set the block on a clean magnetic chuck or vice face before clamping
• Re-index as Needed — rotate the block on its reference faces to machine or grind additional sides without re-centring
