3-1/2″ Square Mag Sleeve 5pc Bitrail

The 3-1/2″ Square Mag Sleeve 5pc Bitrail pairs a longer-reach Square bit set with Railer Magnetic Bit Sleeves on a single rail. Railer includes #1 Square, #2 Square (×3), and #3 Square, all in 3-1/2 inch length, plus Magnetic Sleeves in Sizes 1, 2, and 3. The Mag Sleeve slides over the bit and uses an industrial-strength magnet to hold the screw on the bit during the start, which helps with one-handed drives and reduces cross-threading on framing, decking, and cabinet work where the screw has to start straight. The 5-piece format is a useful fit for users who run square drive screws often and want the magnetic sleeves close at hand on the same rail as the bits.
