Choose the adapter by your drive:

• Cordless screwdriver with 1/4″ hex socket (standard bit holder): Snap Drive 6K M 3 – M 10
• Cordless screwdriver with 7/16″ hex socket: Snap Drive 6K M 5 – M 12
• Reversible ratchet with 1/4″ square drive: Snap Connect 4K M 3 – M 10
• Reversible ratchet with 3/8″ square drive or 19 mm open-end wrench: Snap Connect 6K M 3 – M 12

Then check the square on the tool shank: it must be within the clamping range of the adapter.

The adapter clamps all tools with a square of 2.5 to 5.5 mm:

• Hand taps
• Short machine taps
• Screw extractors
• Tap extensions to DIN 377
• Reamers

The range M 3 to M 10 applies to hand taps to DIN 352. Machine taps, for example to DIN 371 or DIN 376, may have different square sizes. In that case, measure the square.

• Cutting threads in hard-to-reach places, for example in engine compartments, on machine frames or in housings
• Working with a small swing angle: the ratchet keeps cutting where a tap wrench cannot be turned all the way round
• Re-cutting damaged or painted threads
• Removing broken screws with a screw extractor, with the ratchet set to reverse

• Any reversible ratchet with a 1/4″ drive becomes a tool holder, no tap wrench needed
• One adapter for all squares of 2.5 to 5.5 mm (M 3 – M 10)
• Short: only 48 mm between ratchet and tool
• Knurled locking nut for easy tightening
• Robust: body made from a single piece of alloyed tool steel, black oxide
• Engineered in Remscheid, Germany

• Drill the tap hole according to the tap drill size table and countersink it slightly
• Start the tap straight to the hole, with no side pressure for the first turns
• Use cutting oil, especially on steel and stainless steel
• In blind holes and tough material, turn back briefly from time to time to break the chips. Simply switch the ratchet to do this
• Tighten the locking nut firmly so that the tool does not slip
