📘 Overview
The Blue Diamond Tree Auger Bits are tapered tree auger bits skid steer operators use to dig planting holes shaped for balled trees and shrubs. Each bit mounts to a 2″ hex auger-drive interface that fits standard auger drives, and this listing offers dual-diameter (tapered) bits from 18-9″ up to 48-24″ — wide at the top and narrower at the bottom to match a root ball's shape.
This listing covers the tree auger bits in six tapered sizes, from an 18-9″ bit (#105405) up to a 48-24″ bit (#105430). The wide-flute tapered design bores a hole that's broad at the surface and tapered below, ideal for setting balled-and-burlapped nursery stock, and Blue Diamond offers dirt, hard-face, and carbide tree tooth kits to keep them cutting.
As tree auger bits skid steer machines drive, they dig planting-shaped holes fast. Blue diamond tree auger bits taper to match root balls; tree planting auger bits skid steer crews use speed up nursery installs. As wide flute auger bits, the broad flighting clears spoil from the wide hole, and the tapered sizing suits everything from small stock to large trees.
The tapered dual-diameter sizing (18-9″ to 48-24″), 2″ hex drive, wide-flute design, and replaceable tree tooth kits make these purpose-built for tree and shrub planting.

- Speeds up nursery installs — one pass digs a correctly-shaped planting hole, far faster than hand-digging for tree and shrub installation.
- Wide-flute spoil clearing — the broad flighting pulls spoil up and out of the wide hole, keeping the hole clean and the bit digging.

❓ Frequently Asked Questions
Q: Why are tree auger bits tapered?
The dual-diameter taper — wider at the top, narrower at the bottom — bores a hole shaped like a root ball, wide at the surface for the ball and tapering below. That shape lets you set balled-and-burlapped trees and shrubs cleanly, which a straight-sided hole doesn't do as well.
Q: What do the two numbers in the size mean?
The two numbers are the top and bottom diameters of the tapered bit — for example, 24-12″ bores a hole about 24″ wide at the top tapering to about 12″ at the bottom. Match the top diameter to your root ball size when choosing.
Q: Can I use these for regular post holes?
They're optimized for tapered planting holes, so for straight-sided post holes the heavy-duty or cast-head bits are a better choice. Use tree bits when you're planting balled trees and shrubs and want a hole shaped for the root ball.
Q: Are the teeth replaceable?
Yes — Blue Diamond offers dirt, hard-face, and carbide tooth kits made for the tree bits. As teeth wear, you fit a fresh kit rather than replacing the bit. Hard-face and carbide kits last longer in abrasive or mixed soils.
Q: How is shipping calculated?
Shipping is calculated at checkout — add the item to your cart, enter your delivery address, and the shipping charge is displayed before you complete your order. Lift gate service is available for residential deliveries and can be selected at checkout.
