Metallics 00110X Power Bit Insert Bit 10-12 Slotted1" (10pcs)

The Metallics 00110X is a slotted insert bit sized for #10-12 slotted screws, which covers most of the slotted terminal and device screws you hit in panel and box work. It is a 1 inch insert bit, not a longer power bit, so it seats in a magnetic bit holder or an insert-bit adapter rather than straight into the chuck.

Yes. At 1 inch, the 00110X is an insert bit, meaning it has a hex shank on one end only and is meant to drop into a magnetic bit holder or power bit extension. A 2 inch power bit chucks directly into a drill or impact driver; this one does not. If you do not already carry a holder, order one with the bits.

Ten bits per pack, supplied in a pouch. That quantity suits an electrical contractor or MRO crib stocking a consumable, since slotted tips cam out and wear faster than Phillips or square drive and get replaced often rather than sharpened.

Use the slotted 00110X when the fastener head is slotted, which on electrical work usually means older devices, terminal screws, and combination heads you choose to drive flat. The #10-12 size matches the common device and terminal screw range. Where a screw takes a combination head, a Phillips or square drive tip generally holds better under an impact driver because a slotted tip has nothing to resist cam-out.

Order Metallics 00110X. That is the manufacturer part number for the 1 inch 10-12 slotted insert bit sold ten to a pouch, and it is the only configuration under that number.
