Guides
Practical workshop how-tos from the MIS counter - the jobs customers ask us about most.
Removing Broken Screws & Bolts
Seized, rounded-off or snapped screws and studs: freeing the thread, gripping what is left, left-hand drills, screw extractors, and what to do when the extractor breaks.
Identifying a Thread
Metric, UNC, UNF, Whitworth, BSP or NPT? Measure the diameter, gauge the pitch, check the angle and the taper, then look it up.
Setting Speeds & Feeds
Turning a cutting speed into rpm and a feed rate, worked examples for drilling and milling, and adjusting by the sound and the chips.
