Hammers and screwdrivers


Hammers

Club hammer.
Used for general heavy hammering, particularly in building and demolition work. In conjunction with a bolster chisel it is used for cutting bricks, shaping paving stones, knocking through brickwork and so on.

Pin or telephone hammer.
Used for tacks, panel pins, fine nailing and braddling. The wedge shaped end is used for starting small nails while holding them between your fingers.

Warrington or cross pein hammer.
Used for general nailing, joinery and planishing or metal beating.

Ball pein or engineer’s hammer.
Used for metal working. The round end is used for starting rivets, for example. This is the hammer to use for masonry nails as its hardened steel face will not chip.

Scutch or comb hammer.
Used for trimming and shaping common or hard bricks which would damage a brick trowel. The combs can be replaced after wear.

Soft-headed hammer.
Used in metal beating and in general work where it is important not to damage a surface. The soft head also avoids the possibility of a spark setting off an explosion.

Claw hammer.
Used for general purpose carpentry, particularly for driving and removing nails. When taking out nails, make sure the nail head is well into the claw and lever evenly.

Ripping claw hammer.
Used similarly to the claw hammer in work where speed rather than care is essential.

Screwdrivers

Standard slotted screwdriver.
Used for general screwdriving of single slotted screws.

Crosshead screwdriver (Pozidriv or Philips).
Used uith cross slotted screws to provide greater purchase and positive location.

Parallel tip screwdriver.
Used in engineering and otherwise when the screw sits inside a recess of the same width.

Electrical screwdriver.
The insulated handle contains a neon indicator which lights when the blade is touched against a live source. You must ensure that the insulatation is safe for the voltages you intend to check.

Archimedean (or Yankee) spiral ratchet screwdriver.
Used for general purpose screwdriving. Pushing the handle home automatically drives or removes screws. When locked, at length or closed, the ratchet allows screws to be driven or removed without taking the blade from the slot.

The chuck can take blades of different widths and even drill bits.

Double-ended cranked screw-driver
Used for driving awkwardly-placed screws.

Stub screwdriver.
