But i was looking on how to use them no instructions or a guide. by the looks of it must use them separately unless you have 2 collars one for the bit that rotates and other for the chisel portion stationary. I could be wrong but my drill press has only one collar on it and it holds the bit. still a good product. ### ⭐⭐⭐⭐⭐ Really cool tool. *by A***. on June 16, 2020* Have used a few times since they arrived. They work as described. If you take your time and are careful the mortise hole is perfect. Drill bit and square hole punch are extremely sharp, just what you want in this kind of tool. ## Frequently Bought Together - Woodworking Square Drill Bits Set, HSS Wood Mortising Chisel Countersink Bits Woodworker Hole Saw Power Tool Kits 1/4, 5/16, 7/16, 1/2, 5/8-Inch, Set of 5 - Milescraft 1318 DrillMate Portable Drillling Guide – Precision Drilling Jig Attachment for Drilling Angled or Straight Holes, Adjustable Drill Guide Attachment, Portable Drill Press with 3/8” Chuck --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/87132836-woodworking-square-drill-bits-set-hss-wood-mortising-chisel-countersink](https://www.desertcart.at/products/87132836-woodworking-square-drill-bits-set-hss-wood-mortising-chisel-countersink) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-22*
