Borka Tools Precision Screwdriver Bits Kit with 29 S2 Steel Bits, Mini Ratchet, Auto-Lock Holder, and Transport Container SBK
Product Description
Whether you are mounting a new optic on your rifle or making quick adjustments at the range, using low-quality or out-of-spec tools is an easy way to strip a fastener. Standard hex and Torx keys often have loose manufacturing tolerances and soft metal compositions that deform under a heavy load, marring custom screw heads or breaking off inside expensive action chassis recesses. The Borka Tools Screwdriver Bits Kit (SBK) eliminates these maintenance headaches by organizing a professional collection of rugged, dimensionally verified gunsmithing tools into a compact, highly portable layout.
The core of this comprehensive kit is built around 29 premium S2 tool steel bits, which are specifically heat-treated to maximize hardness and prevent twisting during high-torque applications. Each silver-finished bit features sharp, precise edges designed to seat deeply into standard and metric fastener slots, ensuring full surface contact and preventing slipping. For close-quarters work where standard screwdriver handles cannot clear, the kit includes a low-profile mini ratchet handle. This driver gives you smooth, efficient lever action within tight receiver gaps and narrow scope ring mounts.
For added convenience on the bench or out in the field, the kit features a 2-inch magnetic auto-lock bit holder extension. This quick-release sleeve snaps onto your chosen bit automatically, keeping it firmly locked in place so it won't pull loose and drop into a complex trigger group or deep receiver channel while you work. The entire assortment stores securely in a heavy-duty transport container tube made from impact-resistant polymer. Internal dividers keep the bits organized and quiet during transport, making this a perfect standalone maintenance pack to throw right into your range bag or tool kit.
Each individual factory retail package includes one Borka Tools Screwdriver Bits Kit: 29 assorted S2 steel bits, one 1/4" mini drive ratchet, one magnetic auto-lock bit holder extension, a 1/4" hex to 1/4" square drive adapter, and a heavy-duty polymer transport tube.
*Armorer Bench Notes & Technical Maintenance Guidance: The Borka SBK (Part # SBK) is explicitly configured to support standard firearms care and serves as an excellent companion to Borka's preset torque limiters. The 29-piece array provides extensive coverage for SAE Allen Hex, Metric Hex, and common Torx profiles used by major optic brands like Nightforce, Vortex, Leupold, and Seekins. When assembling, make sure the auto-lock collar clicks fully forward to verify the 1-inch bit is locked before applying heavy rotational pressure. To ensure a long service life, keep the mini ratchet clean and occasionally apply a single drop of lightweight synthetic oil to its internal gear tracks. Avoid storing the kit with wet cleaning solvents trapped inside the container tube to prevent surface rust from forming on the bits over time.
