Klein 10-in-2 Insulated Auto-Lock Screwdriver Set (32310INS)

Key Features
1000V Rated
Handles and bits are insulated to 1000V and meet or exceed ASTM F1505 for energized electrical work.
Auto-Locking Collar
Push a bit in and it locks automatically; slide the collar forward to release. No loose bits falling into a live panel.
Slim Insulated Tips
Slim-tip geometry reaches into tight terminal blocks where bulky insulated tips will not fit.
10 Bits, 2 Drivers
A full-size multi-bit and a precision multi-bit share ten insulated Phillips, slotted and square bits stored in the handles.
Overview
The Klein Tools 10-in-2 Insulated Auto-Lock Screwdriver Set (32310INS) brings multi-bit convenience to insulated tools. This is an insulated screwdriver set designed for electricians and technicians working in or near energized environments, rated to 1000V on both the handles and the bits. It includes a full-size insulated multi-bit screwdriver, an insulated multi-bit precision screwdriver and ten insulated bits in Phillips, slotted and square profiles.
Insulation is the core of this set. The 1000V rating covers handles and bits and meets or exceeds ASTM F1505. An orange impact- and flame-resistant insulation layer protects against energized sources during electrical work.
Klein's auto-locking collar keeps bits where they belong: push the bit in and it secures automatically, then slide the collar forward to release it for a quick change. The bits store in the handles, so the set stays together.
Slim-tip geometry is machined for access to tight terminal blocks and confined spaces, a common pain point with insulated tools whose thick insulation will not fit into recessed terminals. The Cushion-Grip handles deliver torque and comfort; the shanks are 4" (10.2 cm), the handles 5-1/4" (13.3 cm) long, with diameters of 15/16" (2.4 cm) and 1-3/8" (3.4 cm) for the precision and full-size drivers. Overall length is 9-1/2" (24.1 cm), and the bits are not magnetic.
Who should buy it: electricians, panel builders, controls and industrial maintenance techs who need 1000V-rated drivers and want fewer tools in the bag.
Insulated From Handle to Tip
Every bit and handle carries 1000V insulation with an orange impact- and flame-resistant layer.
