   / @ajrestoration   Welcome back to another restoration. I bought this Wolf Sapphire drill from an elderly couple on Facebook marketplace. The gears on the drill are worn out and will not be replaced since spare parts are scarce and I do not own a lathe yet. This is purely a cosmetic restoration.

With that said, I hope you enjoy the video.

If you have any suggestions for improvement, or compliments share them below!

Some history on the tool and company.
From the Design Journal editorial, COID Awards 1972, March, 1972. pp.29-34.

Judging by previous years, three people are likely to be killed and nearly 50 injured during 1972 by faulty earthing in portable electrical tools in industry; in the home, 10 people will probably be killed in similar accidents. The majority of fatalities result from a wrongly-connected or loose earth wire coming into contact with a live component; this causes the metal casing of a tool to become part of the circuit, live and therefore lethal.

These faults cannot occur in any of the Sapphire range, for they are not fitted with an earth wire. Instead, every Sapphire tool is double-insulated so that there is no possibility of any part of the casing becoming live.

Double insulation begins with the motor spindle, which has a non-conductive plastics shroud so that there is no possibilty of electrical contact between the gears and the motor. The second level of protection is provided by the casing, which is moulded in impact-resistant grp and is therefore totally non-conductive. The range includes two drills especially made for the home handyman which, with their extensive selection of accessories, are designed to the same high standards as the industrial equipment.

Sapphire range of electrical tools, designed and made by Wolf Tools Ltd; from about £14.70 (domestic) and £16.95 (industrial).

Wolf Electric Tools, London, England
Years ago, I was visiting my parents at their cottage in the Muskokas and they asked me to take some garbage to the local dump. I happened to see an old electric drill hanging from its cord on a fence, so I took it, thinking I could at least use the chuck. It turned out to be made by Wolf Electric Tools from London, England. I'd never encountered a British-made electric drill before. A little TLC and a new cord, and it ran perfectly.
The eponymous Wolf Tools was founded by S. Wolf in 1900, opening their Pioneer Works in Hangar Lane in 1935. They initially produced large cast woodworking power tools and at at one time had a Royal Seal for being suppliers to the British Court. They produced their first DIY electric drill, the "Cub," in 1949, before Black and Decker had even entered the British market. Below, a Wolf "Cub Master" that was being advertised on Kijiji.
By the 1970's, they made a variety of power tools, such as the Wolf PH3 Portable Planer.
In 1978, they employed 850 people. The company was purchased by Kango Tools Ltd. out of Peterborough, England in the 1980's. The Wolf name disappeared as the Kango line was "rationalized," as the euphemism goes. Kango was acquired in turn by Atlas-Copco. In the early 2000's, Kango was sold to a Hong Kong firm, TI. The Wolf factory in London is long since gone, although imitations of their products may have been made under license by a firm in India.
