Counterbore End Mill Cutter
How many recessed lights does an installer install each day?
At least 20. Sometimes 50.
Each light requires one hole. If the hole is made quickly, installers can complete more jobs and earn more money. If the hole is clean, the homeowner is satisfied and is more likely to call again.
So this hole saw is a tool that helps installers increase efficiency and income.

Made for Plasterboard Ceilings
This Counterbore End Mill Cutter is designed for plasterboard ceilings. The blade is made of alloy steel and is very sharp. The cut is smooth and stable, with no shaking. The hole is clean, so the light fits perfectly-neither too loose nor too tight.
There is a center drill. When starting, the center drill enters first and holds the hole saw in place. No wandering. The biggest concern for installers is slipping. A slip can create a crooked hole, and a crooked hole means the light will not fit properly. This tool prevents slipping.
The chip removal holes are large, allowing dust to fall out naturally. No clogging or jamming.
