Types of ScrewdriversScrewdrivers date back to the mid seventeenth century, when they were called “turnscrews”. (In modern French and Dutch they are still know as that, eg. Tournvis in French. In other modern European languages they are called the equivalent of unscrewers or screw-pullers.)

Types of Screwdriver Tip

Paint Brushes

SMall and Large Paint BrushesA good paint brush can last you for many years given the proper cleaning and storage following use. You can always buy a cheap, throwaway brush for one usage only, but a high quality paint brush will hold more paint, apply it smoother, and will not shed so many bristles.

Adjustable Wrench

Wrenches and Adjustable Wrenches ToolboardAdjustable wrenches are commonly of the open ended type, and have one movable and one fixed jaw. With and infinitely variable adjustability within their limits, these tools will fit a wide array of bolt and nut sizes, types and thread systems. On the downside, they are bulkier and heavier than fixed wrenches, a fact which is made up for by being able to dispense with a complete set of tools for one.

Hand Drills

Used for drilling holes in both metal and wood, the hand drill (also called a wheel brace) has been displaced in many woodworking shops by the cordless power drill. They still have many uses, and are available at good prices relative to power drills.

Hand drive and gearing ratios together allow for a wide range of speeds applicable to different types of work and materials. A main gear wheel, cranked by the drive handle, in turns drives a single or double pinion that transfers drive to the chuck.

Carpenter’s Brace Drill

Rusty Brace DrillBrace drills, also known as bit braces, can be traced back to the early 15th century and their use by carpenters in Europe. The brace drill has it’s handle offset to the axis of rotation. Before they were introduced, carpenters drilled holes in wood by turning augers or gimlet bits in repeated rotations via handles.

The brace drill enabled continuous turning and made for quicker boring of holes. Early drills used low efficiency bits of shell or spoon shape; screw shaped auger bits first appeared around 1800. Also slow to develop was the modern springed-jaw chuck with it’s screwed shell, which came in around 1865.
