Why are lubricants used in deep hole drilling?
Friction creates heat, and heat build-up in the drill bit can cause failure and breakage. Lubricants help dissipate heat from the tip of the drill bit, prolonging drill life, and should always be used when deep-hole drilling. Another technique that should be used when deep-hole drilling is pecking."See all results for this questionWhy are low alloy steels not considered high strength steels?High-Strength Low-Alloy Steels Introduction and Overview High-strength low-alloy (HSLA) steels, or microalloyed steels, are designed to provide better mechanical properties and/or greater resistance to atmospheric corrosion than conventional carbon steels. They are not considered to be alloy steels in the normal sense because they areSee all results for this questionWhat makes a hole a deep hole drilling?Holes that qualify as deep-hole drilling" are three or more drill bit diameters deep. When drilling this deep, the speed and feed rate must be adjusted to reduce friction.

Plastic Joining of Ultra High Strength Steel and Aluminium low alloy and high strength sheet Hole drilling
Jan 01, 2006 · Abstract. Ultra high strength steel and aluminium alloy sheets were plastically joined by a self piercing rivet driven through the upper sheet and spread in the lower sheet with a die. The self piercing rivet directly pierces into the sheets without drilling the sheets beforehand unlike the conventional rivets.NITRONIC 60® (Alloy 218) (UNS S21800) Wear and Galling low alloy and high strength sheet Hole drillingNitronic 60s uniform corrosion resistance is better than 304 stainless in most environments. The yield strength of Nitronic 60 is nearly twice that of 304 and 316 stainless steels. Chloride pitting resistance is superior to that of type 316 stainless; Nitronic 60 provides excellent high temperature oxidation resistance and low temperature impact. Applications using Nitronic 60 are valve stems, seats, and NITRONIC 60 High Strength (UNS S21800) - HPAlloyMost published High Strength Nitronic 60 data is based off testing done with 0.5" or less diameter wire that is Cold Drawn and tested at the center.
