Why this one

Step-up and reducing adaptors

Covers common drive sizes from 1/4 to 1 inch, so you can run a socket on a different drive size than your ratchet.

Hex bit holders and couplers

Includes hex bit holders and couplers in various lengths, with regular, magnetic and quick chuck holders for 1/4 hex bits.

Chrome vanadium to DIN

Chrome vanadium steel, designed and manufactured to DIN standards. The 17 pieces weigh 2.8 lb (1286 g) as a set.

TT1 tray storage

All 17 pieces are organized in a TT-Series module size 1 (TT1) tool tray, so every adaptor has its place.

Read the full description

The Teng Tools TTADP17 is a 17 piece socket adapter and bit holder set in a TT-Series module size 1 tool tray. Teng Tools describes it as a wide selection of adaptors, hex bit holders and couplers in one set, with a full range of converters from 1/4 inch to 1 inch drive, designed and manufactured to DIN standard.

The drive adapters work in single steps. Step up: 1/4 F to 3/8 M, 3/8 F to 1/2 M, 1/2 F to 3/4 M and 3/4 F to 1 M. Reducing: 3/8 F to 1/4 M, 1/2 F to 3/8 M and 3/4 F to 1/2 M. With one socket adapter for each step, the ratchet, breaker bar or T bar you already have can turn the socket the job calls for.

For 1/4 inch hex bits there is a quick chuck bit holder 50 mm, magnetic bit holders 50 mm and 70 mm, a 1/4 inch drive hex bit coupler and a 3/8 inch drive hex bit coupler. That gives you a bit holder for drill and driver use and a way to put the same hex bits on a ratchet.

Going the other way, three 1/4 inch bit adapters drive 1/4, 3/8 and 1/2 inch sockets from a hex chuck, and two hex socket adapters convert 1/4 inch hex to 1/4 inch drive (25 mm) and to 3/8 inch drive (32 mm).

The TT1 tray has a PS inlay with a marked position for every piece, so a missing adapter is obvious at a glance. It measures 265 x 142 x 50 mm (10.4 x 5.6 x 2.0 in) and weighs 1286 g (2.8 lb) with all pieces in place.

What you get: four step up adapters, three reducing adapters, one quick chuck bit holder, two magnetic bit holders, three hex shank bit adapters for 1/4, 3/8 and 1/2 inch sockets, two hex socket adapters and two hex bit couplers, in a TT1 tray. Sockets, bits, ratchets and drills are not included.

  • Four step up adapters take each drive up one size: 1/4 inch F to 3/8 inch M, 3/8 inch F to 1/2 inch M, 1/2 inch F to 3/4 inch M and 3/4 inch F to 1 inch M. That is a 1/4 to 3/8 socket adapter and a 3/8 to 1/2 socket adapter for everyday work, plus the larger pair for moving up to 3/4 and 1 inch drive sockets when a fastener needs the bigger drive.
  • Three reducing adapters bring each drive down one size: 3/8 inch F to 1/4 inch M, 1/2 inch F to 3/8 inch M and 3/4 inch F to 1/2 inch M. Use a 1/2 to 3/8 socket adapter or a 3/8 to 1/4 socket adapter when the ratchet or breaker bar in your hand is bigger than the socket the fastener needs, and keep working without fetching another handle.
  • A 1/4 inch quick chuck bit holder 50 mm (2.0 in) long, and two 1/4 inch magnetic bit holders, 50 mm (2.0 in) and 70 mm (2.8 in) long. Teng Tools specifies regular, magnetic and quick chuck holders for use with 1/4 inch hex bits, so the right hex bit holder is on hand for a short reach, a longer reach or a fast bit change.
  • Three 1/4 inch bit adapters drive 1/4, 3/8 and 1/2 inch sockets from a 1/4 inch hex chuck, which makes the set a drill socket adapter kit for running sockets from a cordless drill or driver. Two hex socket adapters, 1/4 inch hex to 1/4 inch drive 25 mm (1.0 in) and 1/4 inch hex to 3/8 inch drive 32 mm (1.3 in), add two more ways to connect.
  • A 1/4 inch drive hex bit coupler and a 3/8 inch drive hex bit coupler hold a 1/4 inch hex bit on a ratchet, so the 1/4 coupler is a 1/4 square drive to 1/4 hex bit adapter. All 17 pieces sit in a PS inlay in a TT-Series module size 1 (TT1) tray, 265 x 142 x 50 mm (10.4 x 5.6 x 2.0 in), 1286 g (2.8 lb) loaded.
