Which of the following most accurately describes the problem?

G & J Hall have added a fourth tool to their Conecut HSS sheet and tube drill range. Using the No 4 drill as a follow-on tool, holes up to 2.125in. can be cut.

A minimum diameter of 1.5in. (38mm) is cut away using a No 3 Conecut and then the No 4 tool is used on the second stage operation to increase hole size.

The drill "bits" are best used with hand-operated electric drills on materials up to 0.0801n. (2mm) thick. Drill shank sizes are 0.375in. or 0.5in. diameter depending on type.

Made by: G & J Hall Ltd, Burgess Road, Sheffield, S9 3WD.
