A cold chisel cuts or shears cold metal, such as seized nuts, bolt heads, rivets and sheet, when struck with a hammer. Cold Chisels lists octagonal shank types in sizes such as 10 x 100mm, 25 x 250mm and 25 x 400mm, some with a hand guard to protect the hand holding the chisel.
A brick bolster has a wide blade for cutting bricks and blocks cleanly along a line; those listed are 225mm long with 75mm or 100mm blades. An electrician's bolster is narrower, listed at 225 x 60mm, and suits lifting floorboards and cutting chases for cable. A 50mm mason's bolster is also listed, and several come with a hand guard.
The shank must match the tool holder. The Chisels section lists SDS Plus and SDS Max shanks, 7/8 inch hex, and chisels named for particular breakers such as the Kango 637, Bosch 11304 and Makita HM0810. SDS Plus and SDS Max are different sizes and do not interchange. Then choose the tip: point, flat, 50mm wide or comb.
A parallel pin punch has a straight shank for driving pins out of holes; choose a diameter just under the pin size. Those listed include 3mm, 6mm and 8mm metric and 3/16 and 1/4 inch, in 150mm and 200mm lengths. A centre punch has a pointed tip to mark a start point for drilling, and an automatic centre punch needs no hammer.
It means the steel runs through the handle to a striking cap, so the chisel can be struck with a hammer rather than only a mallet. Among the carpenters chisels, hammer-thru wood chisels are listed from 6mm to 32mm wide and soft grip pound thru bevel edge chisels in widths such as 16mm, 25mm and 38mm.
Contents vary, so check the piece count in the name. Punch and Chisel Sets includes 11 and 12 piece punch and chisel sets, parallel pin punch sets of 4, 5 and 6 pieces, an 8 piece brass pin punch set and a 3 piece bolster and chisel set. Brass punches are softer than steel, so they are less likely to mark the part.
Bolsters, Chisels and Punches
This category covers striking and cutting hand tools for metalwork, woodwork and masonry. Pages include cold chisels, carpenters chisels, general chisels, brick bolsters, punches, punch and chisel sets, and letter and number stamps. The range takes in octagonal shank cold chisels, some with hand guards, parallel pin punches, automatic centre punches, nail sets, breaker chisels and sharpening stones for maintaining cutting edges.
Brands include Draper and Sealey. Choose the tool type by material first: cold chisels and pin punches for steel, carpenters chisels for timber, and bolsters for cutting bricks and blocks. Then check blade width or punch diameter and overall length, and consider a set where a range of sizes is needed for general workshop use.
