Many variations of the shape of steel drills for glass have been described— from Faraday who used the ground end of a triangular file to C. V. Boys who designed a special drill of tool steel—while other workers (B. Brown, 1927 N. G. Heatley, 1938) advocate the use of a normal twist drill. These drills are used in conjunction with some lubricant—usually the traditional camphor in turpentine, although pure turpentine or other mobile liquid seems to be as good, while Heatley states that dilute sulphuric acid is effective. To avoid splintering, the hole should be drilled from both sides. [Pg.47]

The cap for the fuse hole is drilled from both sides with any high-speed steel industrial twist drill bit. The bit is used with any electric hand or table drill. [Pg.45]
