Pros
- Deep 2-inch reach eliminates the need to drill from both sides of standard doors
- High cutting efficiency with noticeable vibration reduction
- Includes fitted arbor with easily replaceable pilot drill bit
- Durable tooth profile resists dulling on dense materials
Cons
- 3/8-inch hex shank is incompatible with 1/4-inch quick-release impact drivers without an adapter
- Threaded arbor connection lacks indexing drive pins
The Starrett Deep Cut Hole Saw (model ADCH0112) is an industrial-grade cutting accessory engineered for tradespeople, woodworkers, and discerning DIY enthusiasts. Sized at 1-1/2 inches in diameter and boasting an extended 2-inch cutting depth, this tool is purposefully built to handle tasks that standard 1-1/2-inch deep hole saws struggle to complete in a single pass, such as boring through thick solid core doors, countertops, and heavy structural timber.
Real-world cutting performance is driven by Starrett's proprietary NVP progressive pitch tooth technology. The variable tooth spacing continuously varies the chip load, which cuts down harmonic vibration and promotes rapid chip evacuation. Whether penetrating dense laminated particle board, fiberglass hulls, or mild sheet metal, the saw bites smoothly without aggressive grabbing or surface splintering.
Build quality reflects Starrett's precision tool heritage. The teeth are crafted from high-grade, heat-resistant bi-metal high-speed steel welded to a tough alloy body. This construction resists premature wear and tooth stripping when encountering tough knots or metal tubing with wall thicknesses over 1/8 inch. Additionally, the included fitted arbor features a sturdy pilot drill bit that remains securely anchored via an Allen set screw.
One key consideration for users is the mounting setup. The integrated arbor utilizes a 3/8-inch hex shank, which requires a standard 3/8-inch or 1/2-inch drill chuck and cannot directly plug into 1/4-inch hex impact drivers. Because it relies on a threaded fit rather than separate drive pins, users drilling high-resistance materials should ensure the saw is fully seated before applying heavy feed pressure.
Overall, the Starrett ADCH0112 is a dependable, high-performing hole saw that delivers accurate, clean-edged bores with minimal effort. Its deep-cut capacity and long tooth life make it an outstanding addition to any professional tool kit or home workshop.
