IDEAL Industries Tamperproof Torx Insert Bit, Carded

Three tamperproof Torx sizes: T20 (78-0230), T25 (78-0231) and T27 (78-0232). All are 1 inch insert bits with a 1/4 inch hex body.

Tamperproof Torx bits have a center hole to clear the pin in a pin-in-Torx (tamperproof) fastener head. Because the hole is in the center of the bit, these will also engage standard Torx heads of the same size, but they are made for the pinned heads you find on security fixtures, panel covers and institutional hardware. If all you have is plain Torx screws, a standard Torx bit gives fuller engagement.

No. The Milwaukee 48-32-4310 is a SHOCKWAVE double-ended PH2/SL #10 bit, so it drives #2 Phillips and a #10 slotted fastener. The IDEAL 78-0230 is a 1 inch tamperproof Torx T20 insert bit, which has the center pin clearance needed for pin-in-Torx security fasteners. Neither driver tip will engage the other's fastener, so the Milwaukee is not a replacement for tamperproof Torx work.

S2M tool steel with a custom heat treatment for strength and durability, made in the U.S.A. IDEAL machines them to tight tolerances so the bit bottoms fully in the fastener recess, which is what keeps a security Torx head from stripping. For a crew doing repeated removals on security screws, that fit matters more than the bit length.

The IDEAL 78-0230 series is a 1 inch insert bit built for multi-bit screwdrivers and drills, with no impact rating stated. If you are running an impact driver, the Milwaukee 48-32-4310 SHOCKWAVE is an impact duty bit, though it is a double-ended PH2/SL #10 driver, not a tamperproof Torx. For pinned security Torx heads, the IDEAL bit is the one that fits the head.

The Rack-A-Tiers 70241BL is a #2 Phillips screwdriver bit in a 4 inch length from the 702 Series, finished in blue. It covers the #2 Phillips fasteners, while the IDEAL 78-0230, 78-0231 and 78-0232 tamperproof Torx insert bits cover the T20, T25 and T27 security fasteners. The IDEAL bits are 1/4 inch hex body and fit standard multi-bit screwdrivers and power drills, so both can run off the same driver.

Length and tip type. The IDEAL 78-0230 is a 1 inch tamperproof Torx T20 insert bit with a retaining ring notch, made from S2M tool steel with a 1/4 inch hex body. The Rack-A-Tiers 70160G is a 70 Series #1 square Robertson bit in a 6 inch length, so it reaches into recessed boxes and drives square-drive fasteners rather than Torx. Choose by the fastener head first, then by whether you need the reach of a 6 inch bit or the compactness of a 1 inch insert.

The Milwaukee 48-32-4310 is an impact duty bit in the SHOCKWAVE series, built for impact drivers, but its tips are PH2 and SL #10. The IDEAL 78-0230, 78-0231 and 78-0232 are tamperproof Torx T20, T25 and T27 insert bits, custom heat treated from S2M tool steel and rated to fit standard multi-bit screwdrivers and power drills. If the fastener is a tamperproof Torx, the IDEAL bits are the only one of the two that will engage it.

The IDEAL tamperproof Torx bits are 1 inch insert bits, so reach comes from the holder or screwdriver you put them in rather than the bit. If you need a long bit that reaches on its own, the Rack-A-Tiers 70160G is a 6 inch #1 square Robertson and the 70241BL is a 4 inch #2 Phillips, but neither is a tamperproof Torx. For deep security Torx screws, pair this insert bit with a long 1/4 inch hex extension or holder.

Carded, one bit per card, ordered by size: 78-0230 for T20, 78-0231 for T25, 78-0232 for T27. That card format hangs on a pegboard and keeps the size marking with the bit, which is what you want in a shop stocking all three sizes side by side.
