Arbor & Pilot Drill Set with 19 hole saws

This Malco HHA5 set supplies 19 carbide-tipped hole saws plus a quick-connect arbor and interchangeable pilot drills. It is built for tradespeople who need to bore through wood, wall tile, fiberglass, plastic and fiber-cement siding in a single job. The quick-change hex-shank pilots swap between high-speed steel and carbide tips without tools.

Practical limits of the quick-connect system

The arbor locks both pilot drill and hole saw with a hex shank that resists spin-out in thick or layered material. Deep gullets on the carbide teeth clear dust automatically, but the mechanism adds length so very shallow cavities may not accept the assembly. Cutting speed drops noticeably once the carbide tips meet dense aggregate in cement board.

Check your drill and material before ordering

Verify that your drill chuck accepts the arbor shank diameter and delivers enough torque for 19 large-diameter cutters. Confirm the workpiece thickness allows full pilot engagement before the hole saw teeth contact the surface. Buyers who need diamond-grit edges for ceramic or stone, or who require a wider range of diameters than the 19 supplied, should look elsewhere.

Questions about this item

Which version of the Malco HHA5 arbor and pilot drill set should I choose?

The set is offered as a single configuration containing the Quick Connect Arbor and pilot drills, so there are no alternative versions or capacities to select.

What does the 19-hole-saw count mean when I use the set on a job site?

It provides 19 individual carbide-tipped hole saws with self-cleaning deep gullets, letting you cut a wide range of diameters in wood, tile, fiberglass, plastic and fiber-cement siding without changing tools.

What interface does the Quick Connect Arbor use and what does it limit in practice?

The arbor uses a tight-gripping hex shank that locks both the pilot drill and hole saw securely, limiting slippage during high-torque cutting in thick or layered materials.
