Sutton H112 UA1 Universal Arbor Holesaw - Suits 14-30 mm - 1/2 in UNF - 7/16in Hex

The Sutton H112 UA universal arbor is a 7/16 in hex shank holesaw arbor in three sizes: the UA1 for 14 to 30 mm holesaws (1/2 in UNF), the UA2 for 32 to 54 mm holesaws (5/8 in UNF) and the UA3 for 32 to 152 mm holesaws (5/8 in UNF). All three suit a 13 mm chuck.

The self locating drive pins are designed for a stronger torque and driving action, and the thread pattern is made to the international standard to fit holesaws with a 1/2 in UNF or 5/8 in UNF thread. The hex shank is designed to give a positive drive with no slippage in the chuck. Each arbor takes a 6.35 mm (1/4 in) pilot drill.

Sizes and item numbers

Choose the arbor by holesaw diameter and thread.

Using the product

• Match the arbor thread (1/2 in UNF or 5/8 in UNF) to the holesaw before fitting.
• Fit the pilot drill so it protrudes beyond the holesaw teeth, to set the centre of the hole.
• Check the chuck is tight and the arbor is running true before starting the cut.
• Start at a low speed and keep the drill square to the work. Use cutting fluid when cutting steel.
