✔️ 5/16-18 HSS Drill Tap, 1/4" Hex, 3.25" OAL, RH Cut, With Case
This handy multipurpose bit handles drilling, tapping, and countersinking in a single pass to slash setup time on 5/16-inch by 18-thread fasteners. Built with hardened HSS steel against 10-gauge metal, the tool cuts clean threads and clears burrs without needing extra passes or swappable accessories. The 1/4-inch quick-change hex shank locks tight in drills while the back-tapered design stops cross-threading risks during deep pulls. Comes complete with a rugged plastic storage case and matching adapter so you swap sizes faster during busy shifts without worrying about lost parts.
P ✅ 5/16-inch by 18-thread size supports standard fastener requirements across metal fabrication. ✅ Right-hand cutting action matches common drill pressure direction for smooth threading. ✅ Hardened high-speed steel body resists heat buildup better than carbon steel options. ✅ 3.25-inch overall length offers extended reach for deeper hole access without wobble. ✅ 1/4-inch quick-change hex shank grips securely inside drill chucks for straight power transfer. ✅ Back-tapered section past the tap area protects finished threads from debris damage. ✅ Full deburring and countersink profile clears sharp edges and blends flush surfaces instantly. ✅ Rated to handle up to 10-gauge metal thickness during aggressive driving cycles. ✅ Package ships with protective storage case plus companion adapter piece for hassle-free transport.💡 Why select a three-function drill tap bit rather than switching between separate tools for pre-threaded metal work?
This handy multipurpose unit eliminates multiple tool swaps while delivering accurate results directly on active job sites.
- Integrates clearance drilling with thread-forming grooves to create clean internal pitches before engaging metal stock.
- Features an integrated countersink profile behind the tap section that shaves off sharp burrs for flush nut contact.
- Utilizes high-rigidity shank geometry to minimize runout which prevents crooked threads during heavy-duty driving cycles.
- Designed with reinforced flutes that evacuate chips efficiently when cutting through thick gauge alloys up to specified limits.
