FOOD & BEVERAGE Stainless and Mild Steel Drilling CRYOBIT® DRILL BITS APPLICATION STORY • Maintenance groups in most food and beverage plants face the same challenge: drilling stainless. While stainless is not a hard metal, it will harden quickly if it is not drilled properly. • Some use cobalt bits to drill stainless, but these bits have a thick web and will not pass bulky chips (like aluminum and mild steel). Standard HSS bits typically dull quickly drilling stainless. A major non-dairy creamer production facility directed their maintenance group to test Cryobit drill bits against “premium” HS and cobalt drill bit samples from four companies. FEATURES AND BENEFITS • After extensive testing, they concluded Cryobit drill bits possess • Designed to be tough enough for abusive hand the toughness and diversity they require. Cryobit drill bits drilled up to 6 times more holes in stainless steel. Additionally, drilling yet open enough to pass large softer chips they found Cryobit drill bits to be perfect for drilling softer without binding metals like carbon steel and aluminum. • 50% Flute resists breaking caused by excessive flexing TIPS FOR DRILLING STAINLESS STEEL Drilling stainless requires 50% more feed pressure than • CM-8™ alloy steel combines with the patented mild steel and a reduced RPM. Cryophase™ treatment to help keep the drill bit sharp in the toughest applications Stainless steel work-hardens up to 45 Rockwell-C in some cases • 3-Flats on the drill bit shank makes these bits perfect • Too little feed pressure work- for keyless chucks commonly found in hand drills hardens the immediate drilling surface Cryobits can be used by hand • Available in 29 piece jobber lengths to 1/2'' and in • A dull bit will work-harden or in drill presses… the immediate drilling surface reduced shank bit sizes up to 1-5/16'' • A center punch work-hardens the starting divot • Pilot holes are NOT beneficial when drilling stainless because they can work-harden the hole Always use cutting fluid for drilling stainless to promote cleaner hole finish and double …or lathes. bit life.
