(The tips were drawn to a permanent magnet that I placed near them.) **Q: Is this a microbit set?** A: The Wiha site lists this as a "System 4 ESD Safe Micro Bit Interchangeable Set with ESD Handle and Slotted, Phillips, Torx®, Hex Inch Micro Bits. 105mm Bit Extension. 27 Piece In Rugged Metal Box" **Q: The lid does not close properly, the handle diameter is just too large. Is that a problem with a newer model, the one with yellow handle?** A: Yes,, the magnetic Picofinish yellow handle now sold with 75992 is too thick to completely close the lid on the left side but it almost does. Got mine 8/20/2021. i also treated bits with Xerox to prevent rust as some have had on their bits after a while.. ## Frequently Bought Together - Wiha 75992 System 4 Precision Interchangeable Bit Set, Torx, Slotted, Phillips, Hex Inch, ESD Safe Precision Handle, 27 Piece In Compact Box - KNIFE PIVOT LUBE Original Knife Oil for Blades, Synthetic Pocket Knife Lubricant, Knife Honing Oil for Cleaning Knives, Premium Knife Oil Lubricant for Blade Care, Precision Knife Oiler Bottle (10ml) - LOCTITE 248 Blue Threadlocker Glue Stick: All-Purpose, Medium-Strength, Anaerobic, No Drip, General Purpose, Works on all Metals | Blue, 9 Gram Wax Stick (PN: 37643-506166) --- ## 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.co.uk/products/255371668-75992-system-4-precision-interchangeable-bit-set-torx-slotted-phillips](https://www.desertcart.co.uk/products/255371668-75992-system-4-precision-interchangeable-bit-set-torx-slotted-phillips) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
