Resolution rather than range. A 10 blade set gives coarse steps and a 32 blade set fills in between, which matters when a clearance falls between two blades.

It has to match the specification being worked to. Dual marked blades carry both, which removes the conversion and the risk of getting it wrong at the engine.

One with blades stepped round an obstruction, so the gap can be reached where a straight blade would foul something before arriving at the clearance.

An angled gauge for valve clearances, which reaches under a rocker where a straight blade cannot be presented squarely to the gap. The 12 blade version carries metric and imperial.

With extra long blades. A 26 blade extra long combination set reaches a clearance set deep in an assembly where a standard blade runs out before it gets there.

Yes, where a clearance falls between two sizes, though a set with more blades reduces how often that is needed. The gauge is read by feel rather than sight, so a clean entry matters.

Blade count is really a measure of resolution rather than range. A 10 blade set gives coarse steps and a 32 blade set fills in between them, which matters when a clearance falls between two blades and has to be made up by stacking. A blade that is close but not exact reads as a pass when the clearance is actually wrong.

Marking has to match the specification being worked to. A metric-only set is no use against an imperial figure and the reverse is equally true. Dual marked blades carry both, which removes the conversion and the risk that comes with doing it at the engine. A dual marked set also removes the need to keep two sets and pick the right one under a bonnet.

Blade form decides whether the gauge reaches the gap at all. A straight blade suits an open clearance. An offset blade steps round an obstruction. An angled tappet gauge reaches a valve clearance under a rocker where a straight blade cannot be presented squarely. Sealey hold 12, 13, 26 and 32 blade sets with Draper covering the same span in metric and imperial.

Extra long blades at 26 blade combination reach a gap set deep in an assembly, where a standard blade runs out before it arrives. A gauge is read by feel rather than sight, so the blade has to enter cleanly. Send the clearance specification to 07754288583 on WhatsApp. Blades are thin enough to bend if forced, which is why the right form matters more than the count.
