The Borka Tools Torx 2" Length S2 Bit Set (Model: T-2-6PC) is a 6-piece driver accessory pack engineered for precision firearm assembly, optic mounting, and general bench maintenance. Manufactured from heat-treated, shock-resistant industrial-grade S2 tool steel (HRc 58–60), each bit features an extended 2-inch (50.8 mm) overall length and a standard 1/4" hex shank. This extended length provides direct clearance to recessed screw wells, optic rings, and chassis fasteners without the need for thick, separate bit extensions or adapters that can introduce wobble during critical torque applications.

Key Features

• Extended 2-Inch Reach: Provides direct access to deep counterbores, scope turret clearances, and recessed action fasteners where standard 1-inch bits cannot reach.
• Industrial S2 Tool Steel: Heat-treated and hardened to HRc 58–60 for high torsional strength, precise fastener engagement, and resistance to cam-out or stripping under torque.
• Universal Drive Compatibility: Standard 1/4" hex drive fits manual torque drivers, ratchets (such as the Borka DRIV4 and BTD1070-IP), magnetic bit holders, and standard chucks.
• Defined Torque Capacities: Built with safe working limits ranging from 25 in-lbs (2.82 Nm) on the T10 bit up to 100 in-lbs (11.30 Nm) on the T30 bit.
• Comprehensive Torx Array: Supplies the 6 primary Torx fastener sizes used on modern firearm chassis, scope mounts, and optic bases.

Who is the Borka Tools Torx 2" Length S2 Bit Set for?

• Precision rifle scope installers — requires the 2 inches (50.8 mm) extended length to clear scope turrets and optic ring bells while tightening fasteners sized from T10 to T30 on a standard 1/4" hex torque driver.
• Bench gunsmiths and field armorers — benefits from this 6-piece S2 steel Torx bit set to service recessed action screws and chassis mounts across safe working loads ranging from 25 in-lbs (2.82 Nm) up to 100 in-lbs (11.30 Nm).

Less suitable for: Applications where fastener reach exceeds 2 inches (50.8 mm) inside deep rifle channels; tasks requiring deeper access are better served by dedicated 4-inch extra-long reach bits or a 3.5-inch bit extension.
