EASILY ENLARGE EXISTING HOLES WITH PRECISION AND SPEED

Eliminate the frustration of trying to widen a drilled hole without a center point using the Bosch HE1 2-Piece Hole Enlarger Kit. This ingenious accessory is the ultimate problem solver for electricians, plumbers, and remodelers who need to increase the diameter of an existing hole without damaging the surrounding surface. By allowing you to mount two hole saws simultaneously—using the smaller saw as a pilot guide for the larger cutter—this kit ensures perfectly concentric, clean enlargements every time.

Part of the patented Bosch Quick Change™ Universal Hole Saw System, the HE1 is designed to help you work faster and smarter. The integral adapter facilitates rapid saw changes and simpler plug removal, keeping your workflow efficient. Whether you are upgrading recessed lighting or resizing pipe pass-throughs, this kit includes the necessary adapters and washers to fit a wide range of hole saw sizes, making it a versatile addition to any professional toolkit.

Key Features

  • Precision Hole Enlargement: Allows two hole saws to be used together to perfectly center and enlarge existing holes.
  • Quick Change Compatibility: Integral adapter design supports fast accessory changes and tool-free operation.
  • Universal Fit: Works with standard hole saw mandrels and fits any brand of tool.
  • Secure Stacking: Includes large and small washers to securely mount different hole saw sizes together.
  • Easy Plug Removal: Design facilitates easier ejection of the material plug after drilling.
  • Durable Construction: Built to withstand the torque and pressure of heavy-duty drilling applications.

Manufacturer Bosch
Model Number HE1
Product Type Hole Saw Enlarger Kit
System Compatibility Quick Change™ / Universal

Application Enlarging Existing Holes

Pro-Tip: When using the enlarger, the smaller hole saw (the "pilot") should be the same diameter as the existing hole, and the larger hole saw should be the diameter of the new desired hole. Because you are spinning two saws at once, use a lower RPM and a firm two-handed grip on your drill to maintain control and prevent binding.

I have 2!
Color: Coal Black
My office is in my loft. But there are things along the wall I don’t want to look at. These work great. Hides what I don’t want to see & is a classy look in the room. Sturdy, easy to assemble, well made.

Good for a quick backdrop
This works well for what I needed – a simple background for my kids’ online school. It’s lightweight and very easy to put together, and it stands up fine without needing to mount anything. The color is listed as black, but it’s more of a dark gray in person. Not a huge deal, just something to be aware of. It’s not super heavy duty, but it does the job for privacy and as a video backdrop. Overall, a good, portable divider that’s quick to set up and works well for light use.
