Heavy-Duty Treehouse Bolt Drill Bits - Kit Rental


These drill bits are intended to be used with our Heavy-Duty Treehouse Attachment Bolts (TAB).  Heavy-Duty TABs will require both a 3" Speedbor and either a 1½" or 1⅝" ship auger.  For our Standard TABs, we offer a specialized drill bit and Speedbor rental kit.

During installation, the inside cutting plane shaves the hole radius for clean smooth holes without pressure. A hex shank provides a secure gripping surface for the drill chuck. The cutting edges on these bits can be resharpened.

A heavy-duty corded drill is recommend when installing treehouse bolts.  If two or more bolts will be installed, a water level is the the easiest and cheapest method for matching the same horizontal plane on the single or multiple trees.  Be sure to compensate the height difference if different brackets will be used on the same platform.

Our Heavy-Duty TAB installation process consists of two stages:

  1. Drilling into the tree with the 3" Speedbor Self-feeding bit.  This is to fit the collar portion of the TAB into the tree.
  2. Drilling into the same hole with a ⅞", 1" or 1⅛" auger bit.  This is to fit the stem portion of the TAB into the tree.
Note: We use several different manufacturers for the supply of our 3" Timberfeed bits. The bit you receive may not be the same as the bit in the images. If you have any questions, please contact us prior to
making your purchase.

Tools & Bits for Sale OR Rental:

Before installing TABs into trees, you need to predrill a multi-stage hole. These bit sizes are generally not kept in stock at home improvement stores. We supply the correct drill bits for TABs in a kit which you can purchase OR rent. We also supply some treehouse bolt tools that are useful for turning the TABs into the tree.

International orders, Duties and Taxes:

International orders may be subject to Duties and Taxes by the receiving country. These Duties and Taxes are the sole responsibility of the recipient. Since the amount varies depending on the country, TreeHouse Supplies, Inc. is not able to estimate the amount prior to shipping the order. If you have questions about Duties and Taxes, you should contact the appropriate government office in your receiving country and determine the amount you will be required to pay. If you refuse to pay the duties and taxes, the shipping company will deny delivery of your order and return it to TreeHouse Supplies, Inc. If this happens we will deduct the cost of the return shipment from your refund amount. If we receive a bill for duties and taxes unpaid by you the customer, we will invoice you for those fees and you are obligated to pay.

We will not ship to freight forwarding companies. We use Fedex to deliver all of our worldwide shipments.


Window Shipping:

FedEx charges by DIM weight not actual window weight. You can click here to see how they calculate the shipment. So for example: Our 24x36 window's actual weight is 20 lbs, however, FedEx will rate the package at 57 lbs. because the box size is 38" x 8" x 26". Please email us if you have any questions prior to ordering.

We may charge a fee if the shipment has to be hand delivered to the commercial shipper. The fee is based on a case by case basis. Some products that require customization or special orders are not available for immediate shipping - i.e. Bridge Kits, Rustic Swings. If you are unsure, contact us for clarification.
