The PTA Canada Ultra-Kut Gold Annular Cutters are built to cut holes in aluminum, mild and stainless steel.

Ultra-Kut Gold Annular Cutters are the industry standard for hole making in heavy-duty applications. More precise than twist drills, these cutters can increase your cutting speed by up to 3x over conventional methods, and leave a reamed quality, burr-free hole.

Gold Series Ultra-Kut™ cutters feature:

• Double action tooth geometry makes cutting faster, smoother and reduces chatter.
• Ground and fully fluted ejection channels provide better chip evacuation requiring less power and improving performance in deeper holes.
• Weldon Shank with two flats for cutting mounting ensures a rigid cutting environment – up to 2x the tool life compared to quick change mounting systems on competitive brands.

Drilling Tips

Gold Series Annular Cutters work best with constant, confident pressure with lubricant or cutting fluid. If the magnetic drill motor is noticeably struggling or the chips produced are blue in color, ease off the pressure. Smaller diameter cutters use higher feed rates than larger cutters. To increase the life of your cutter, use lubricating fluid or sticks.

Caution:

Annular cutters are great for making new holes – but they are lousy at makes holes larger. Attempting to enlarge a hole is the primary cause of cutter breakage. To enlarge a hole, use a reamer or lathe.
