Dth VI missio descendit in foraminis "marmore et frenum pretium"
In aliis applicationibus, ut fundamentum diam, mallei DTH adhiberi possunt una particula in magnitudinum foraminis usque ad .750 mm (30″).Cum malleolo multiplicato unitates CD (terebrarum glomerorum) perforata terebra usque ad 70″ vel 1778 mm.
Pro regula pollicis, minimi foraminis diametri malleus DTH terebrare potest eius nominis magnitudo.A 4 inch malleus terebraturus 4 inch (102 mm) foramen.Terminatio est extra diametrum mallei, quia, ut foramen diametri minuit, airfluxus restringitur.Maxima foraminis magnitudo ad producendam artem est nominalis malleus amplitudo plus 1 pollicis, sic ad 4 pollicis malleus maxima magnitudo foraminis est 5 pollicis (127-130 mm).
Malleus ius eligens late determinatur per foraminis magnitudinem et speciem formationis petrae.Specimen mallei magnitudinem debitam foraminis dimensioni quamproxime aequare debet, tantum spatium relinquens ad incidenda foraminis evacuandam.
