About The Product
Choose Diamax Cyclone CNC Core Bits 1/2 inch Wet Only for CNC Machine. Engineered Stone Granite Core Bit 1/2 Inch Gas Arbor Size 3 Inch Length delivers steady performance for demanding stone fabrication applications. When your CNC setup requires precision and longevity, this core bit stands out for its consistent results in both engineered stone and granite. Every feature, from size to compatibility, is focused on removing guesswork and keeping your workflow as predictable as your deadlines.
The 1/2 inch bit diameter is a staple dimension in the stone fabrication industry, making it a go-to for countertop shops, commercial fabricators, and restoration pros who need a reliable cut every time. With a 3-inch length, you're getting enough reach to drill through slabs and thicker material without introducing extra flex that can throw off hole quality. This balance means it's useful for through-holes as well as deeper recesses; you can move between tasks or stone types without hunting for a new tool every project.
The arbor size clocks in at 1/2 Inch Gas, a familiar spec for most CNC stone machines found in busy shops. This allows for quick swapping and universal fitment, so downtime is kept to a minimum during changeovers. If you've ever had to jury-rig bits or adapt fittings mid-shift, you'll appreciate that these are ready-to-go with the most common CNC spindles and holders out-of-the-box.
This core bit is designed for wet-only use, which is crucial in controlling heat, extending the life of your tooling, and most importantly, producing a smooth, chip-free edge in even the most brittle engineered stones. Dry drilling can give you speed, but with high-end slab materials, wet operation is vital to avoid cracks, excessive dust, or costly rework. The bit holds up under continuous cooling, so if your workflow is all-day batching, you don't have to slow down or compromise quality to protect your investment.
Maximum recommended speed is 2300 RPM, striking the right balance so you get enough speed for efficient material removal without burning up your bit or sacrificing edge accuracy. It's engineered for use with CNC machines-no guesswork about whether it'll keep up with automated, highly repeatable cycles. From first hole to the last in a job run, you get consistent diameter and wall quality, so you don't lose time correcting off-size holes or cleaning up ragged edges after the fact.
The bit is dedicated to use on granite and engineered stone, where regular masonry bits simply don't hold up. If you've tried running general-purpose bits through quartzite or compact granite, you know how quickly they dull or cause unpredictable breakouts. The Cyclone series is trusted across commercial settings because it's specialized-not generic-so tool budget and material cost are easier to manage across big contracts or one-off custom pieces.
Bulk pricing and contractor discounts are available for larger orders, making it easier to keep your bench fully stocked without overspending, and ensuring your team never waits for replacements.
