Jaw Brace with integral ratchet

The hallmark of these braces for manual operation is their high-quality workmanship. Clockwise and anti-clockwise rotation by means of a ratchet. Made in France.


Jaw Brace with integral ratchet and two-jaw chuck

The square shank of the drill bit is held by the two jaws of the brace and does not sit in a square socket as is the case with four-jaw chucks. The drill bit is nonetheless held very firmly. This brace is especially suitable for smaller square shanks from about 5 mm and can be used with square shanks up to 12 mm across measured at the thick end of the shank. Not suitable for straight hexagonal shanks, because the jaws grip the drill bits conically.

Jaw Brace with integral ratchet and three-jaw chuck

For drill bits with a straight hexagonal shank from 5 to 16 mm. Drill bits with hex shanks are readily available in many sizes. It’s the ideal brace for anyone with a stock of modern drill bits. Drill bits are held very firmly by this brace. Also suitable for drill bits with conical square shank! The square shank of drill bit is inserted so that the end of the shank sits in the square socket at the base of the chuck to stop the drill bit from slipping. Less suitable for drill bits with round shanks, as these tend to slip under greater load.

Jaw Brace with integral ratchet and four-jaw chuck

The square shank of drill bit is inserted so that the end of the shank sits in the square socket at the base of the chuck to stop the drill bit from slipping. The drill bit is centred by means of the 4 jaws. The integral ratchet makes it easier to work in hard to reach places. Plastic handles. An outstanding brace for holding drill bits with a square shank. The square socket at the base of the chuck measures 7.5 x 7.5 mm. This dimension determines in part the choice of drill bit. The end of the shank should be slightly under 7.5 x 7.5 mm or filed down to that size. At least at one point the shank should measure 6 mm across to prevent the drill bit from slipping. The thick part of the shank may be up to 16 mm across.

Jaw brace DeLuxe with integral ratchet

Technical realization as above, but enhanced by several details that turn this tool into an aesthetic delight. The burnished steel parts combine with the brass sleeves to create an optically stunning overall impression. Crank handle and head are made of kotibé, a fine-grained, mahagoni-coloured wood.

Jaw Brace with plastic handles

This jaw brace has a four-jaw chuck, which means that the bit is clamped by a very reliable mechanism with four jaws. There is an integral ratchet to make drilling easier in confined spaces. Handles made of black plastic. An ideal brace for square-ended bits (as found on our spiral bit page), which are gripped immovably. Because the brace is designed to take bits with a square-ended shaft that fits into a square ( 8 x 8 mm) socket at the base of the chuck, bits with round shafts are held in place only by pressure from the four jaws in the chuck. Round bits will tend to slip when torque is applied using the brace, and so are not recommended. Made in Taiwan.

Jaw Brace with wooden handles

The wooden grips on this jaw brace add a bit of warmth and good looks to this quality tool. The wooden parts are not oiled or finished in any way. We, like many other woodworkers, think this is the best way to treat grips like this, as the wood is free to absorb sweat from one's hands, making the tool many times more comfortable to use. If it is important that the wood not become soiled in use, then one can finish the wood using oil or varnish, for example.

Adapter for small conical square Shafts

Our braces have, at the base of the chuck, a square hole to hold immobile the square end of the shaft of various kinds of bits. The size of the hole is designed to accept the most common sizes of square-ended bits. There are however a variety of square-ended bits that are too small to be securely held in the normal, 8 x 8 mm hole. So if used in this brace, they will be held only by the four jaws and can turn or come loose under pressure. With this simple, inexpensive adapter, this problem can be solved. It is a section of square brass tube (in the photo down and to the right). Placed in the square hole at the base of the chuck, it reduces the 8 x 8 mm hole to 6 x 6 mm to hold smaller bits firmly in place. More...

Tools with conical shaft for use with brace

The brace can be a very versatile tool, given a good choice of bits with square-ended shafts to fit it. Unfortunately the range of these tools currently available is much reduced and many useful bits are now difficult or almost impossible to find. Over the years though, we have made an effort to track down supplies of these kinds of tools, and on our website one can find a relatively wide variety of them, some of which are currently in production, and others that come on the market from time to time, from warehouse sales for instance. We are working to increase the range of these types of tools that we can offer, because we think hand braces are an enormously useful and versatile tool and one that is far too under-appreciated these days.
