Made to the same dimensions as No.150 drills, these blanks are taken from the drill manufacturing process 
and are finish ground to the same tolerance as the drills (ISO h8). They also have drill hardness 
(HR ‘c’ = 62-64) all over and can be used as gauges, drifts, spindles, punches, locating pins and tool blanks. 
They may have squared-off ends or spindle (coned) ends according to diameter, or the manufacturing 
process from which they are drawn. 

The sizes listed here are normally kept in stock. Other sizes may be manufactured to order, in which 
case the quantity ordered will determine the unit price. Tolerances other than h8 may also be delivered
against special order.
