Run the triple op­tion for more im­pact

WOOD - - TOOLS & MATERIALS - —Tested by Michael Springer

Triple Ham­mer 18-volt 1∕4" im­pact driver kit (with two 3.0 Ah bat­ter­ies and charger), no. WH18DBDL2, $345; bare tool, no. WH18DBDL2P4, $200

Hi­tachi’s Triple Ham­mer driver uses a unique mech­a­nism with three ham­mers and anvils (other im­pacts use two) to cre­ate greater torque op­tions for dif­fer­ent fas­ten­ers. It does this via four driv­ing modes: three dif­fer­ent speeds us­ing three im­pacts per mo­tor ro­ta­tion, and one at high speed us­ing only two im­pacts per ro­ta­tion. (In this mode, the ham­mer skips ev­ery other anvil, cre­at­ing a greater “windup” for more force.)

In use, this tool feels just like a tra­di­tional two-ham­mer im­pact, light with a short head that fits eas­ily into tight spa­ces. It has all the power and speed I ex­pect from an im­pact driver, able to sink 4"-long lag screws with ease. But, like most other im­pact driv­ers, it’s loud: 92 deci­bels, well above the thresh­old where you should wear hear­ing pro­tec­tion. It also vi­brates more than I ex­pected dur­ing heavy use.

Note: Shortly be­fore this is­sue went to press, Hi­tachi Power Tools changed its name to Metabo HPT. This im­pact driver, and all other Hi­tachi-branded tools, will tran­si­tion to the Metabo HPT brand­ing over the com­ing months with no other changes, ac­cord­ing to Abby Levy, mar­ket­ing di­rec­tor.
