Fast Cut Hole Saw Enlargement Arbor

SKU: KA19

Fast Cut Hole Saw Enlargement Arbor

Starrett KA19 Hole Saw Enlarger - Purpose-built arbor attachment designed to enlarge existing holes cleanly and accurately without drifting or miss-cutting. By replacing the standard pilot drill on your arbor, the KA19 allows you to attach a hole saw that matches the diameter of your existing opening to serve as a steady guide for a larger outer hole saw.

Featuring a heavy-duty design with dual-thread compatibility, this arbor system ensures precise concentric alignment when resizing pre-drilled holes in various substrate materials. It eliminates the need for makeshift backing plates or timber plugs, streamlining modification work and delivering clean, professional results with minimal effort.

Constructed for high strength and repeated trade use, the Starrett KA19 provides a secure connection between both hole saws during rotation. The inner guide saw fits snugly into the existing aperture to absorb lateral movement, allowing the larger outer saw to cut a smooth, perfectly centred larger opening without damaging surrounding surfaces.

PLEASE NOTE: HOLE SAWS ARE SOLD AND SUPPLIED SEPARATELY
