Klein Tools 6856INS Insulated Screwdriver, #1 Phillips Tip, 6-Inch Round Shank

The 6856INS is a 1000V rated insulated screwdriver with a bright orange impact and flame resistant insulation layer over the shank, and it meets or exceeds ASTM F1505-16(2021) and IEC 60900-2018. Klein's own guidance printed with the tool: only use drivers marked with the official international 1000-volt rating symbol if there is any chance of contact with an energized source. That makes it appropriate for live electrical work within that rating, not a general-purpose driver that happens to have a plastic handle.

Shank length is 6 inches (15.2 cm) and it is a round shank, with an overall tool length of 10.32 inches (26.2 cm) including the 4.31 inch handle. That 6 inch reach gets a #1 Phillips tip down to terminal screws in deep boxes, panel gutters, and behind mounted devices without choking up on the handle. The round shank also means no flats to catch, so it passes through tight knockouts and crowded conductors more easily than a square shank.

The 6856INS carries a #1 Phillips tip, which is the smaller size used on control wiring terminals, thermostat and low-voltage device screws, small appliance and equipment covers, and panel trim screws. Standard receptacle and switch terminal screws and most device plate screws take a #2 Phillips instead, so if you are wiring devices all day, a #2 insulated driver is the one you want on the belt and the #1 is the companion for the small stuff.

Yes, there is a tether hole in the handle for working at height, so it can be attached to a tool lanyard rather than left loose in a bucket or pouch. At 3.6 oz (102 g) it is light enough that a standard small-tool tether handles it without issue.

No. The 6856INS tip is non-magnetic. For starting a loose screw one-handed in an overhead box you will need to hold it by hand or use a separate screw-holding driver. What it does have instead is Klein's Tip-Ident marking on the handle, which shows the tip orientation so you can line the tip up with the screw slot without looking at the business end.

The Cushion-Grip handle is rubber, 4.31 inches long and 1.24 inches in diameter, which is a full-hand grip rather than a stubby or precision handle, and Klein builds it for greater torque and comfort. The handle is also flame retardant and impact resistant, which matters when the tool is being used near energized gear.

It is made in the USA. The ordering identifier is Klein Tools 6856INS, a 1000V insulated #1 Phillips driver with a 6 inch round shank. Spec it that way on a standardized electrical tool kit and the only variable left is tip size and shank length across the rest of the insulated line.

The orange is the insulation itself. Klein uses a bright orange color-coded insulating layer over the steel shank so a 1000V rated tool is visually obvious in a pouch full of uninsulated drivers. The handle under it is black, and the tool is built of steel and plastic with a rubber grip. If the orange is cut, gouged, or worn through to the metal, the tool is out of service.
