What these tools are & how they are used: These are precision straight-shank straight-flute chucking reamers (also called chuck reamers). They are designed to be held in a drill chuck, collet, or floating reamer holder and used after drilling to bring holes to exact decimal diameters with excellent surface finish and tight tolerances. Straight flutes are excellent for general-purpose work, brittle materials, or applications with interruptions. The HSSCo piece offers enhanced performance in tougher or higher-heat materials. Typical applications include aerospace, automotive, tool & die, maintenance, and precision machining.

Condition – Please read carefully: These are used tools showing normal signs of previous industrial use. Packaging is original but taped, scuffed, and worn. Tools have surface residue, minor discoloration/oxidation possible from storage, and visible wear on cutting edges/flutes (some edges appear dull or have minor chips/irregularities per close-up photos). They have not been tested or sharpened by us. Sold AS-IS with no guarantees of sharpness, exact remaining life, or performance. Ideal for machinists who resharpen/hone tools, use for roughing/less critical work, or add to a collection/parts inventory. Review ALL photos closely before purchasing—photos show actual items including labels and tool close-ups from multiple angles.

Why buy this lot? You receive a useful variety of popular decimal sizes in the 1/4"–3/8" range (great for over/under fits or special applications) from a respected brand (Hertel) at a fraction of new cost. Great value for hobbyists, small shops, or anyone needing multiple sizes without buying a full new set.

Important disclaimers: Always wear proper PPE. Verify sizes and condition before critical use. These may require cleaning, inspection, and professional resharpening for best results. No returns on used cutting tools per eBay policy and nature of item. Questions? Message before bidding/buying.
