When you need a wheel that grinds as fiercely on its thousandth cab as it did on its first, nothing beats a sintered diamond wheel.

Engineered with embedded diamonds right in the metal, these wheels are for serious lapidary work - cutting faster, smoother, and far longer than plated or resin-bonded alternatives.

With diamonds embedded throughout a full 3 mm deep matrix, these wheels continuously expose fresh cutting edges as they wear—so your grind stays consistent, your stones shape effortlessly, and your productivity never slows down. Whether you’re tackling hard agates or delicate opals, sintered technology delivers the precision, durability, and efficiency that professional cabbers swear by.

Why Sintered Is the Best Choice
Unlike plated or brazed wheels, which have a single layer of diamond that wears away, sintered wheels contain diamond throughout the entire rim. This means they last many times longer, maintain a consistent cut, and can even be dressed to reveal additional crystal layers for an even sharper bite when needed. For many lapidaries, investing in sintered means upgrading once and enjoying years of reliable performance.

Key Features:

  • Full 3 mm deep diamond matrix exposes new cutting points as you grind

  • Long-lasting performance – outlasts plated and brazed wheels many times over

  • Dressable rim for restoring cutting aggression (optional with proper technique)

  • Balanced aluminum cores for reduced weight, smoother operation, and less vibration

  • Includes multiple bushings (3/4", 5/8", 1/2") for compatibility with most cabbing machines

  • Professional consistency – cuts as well on the first cab as on the last

Specifications:

  • Width: 1.5"

  • Diameters: 6" (150 mm) or 8" (200 mm)

  • Max RPM: 5,700

  • Weight: 6" – 5.7 lb, 8" – 7.5 lb

  • Arbor: 1" OD standard

  • Includes bushings: 3/4", 5/8", 1/2"

Pro Tip: When switching from plated or brazed wheels, choose one grit size coarser for best results with sintered tools.

Note: These wheels are made to order and ship directly from the manufacturer. Please allow 2–6 weeks for delivery.

Upgrade once, grind for years—Inland Craft Sintered Diamond Wheels are the smart, long-term choice for high-volume cabbing.

I had a great experience working with Craig. I needed to change my order and they were already aware of my mistake with the saw size. Everything was so easy and smooth.

CabKing Grinder with attached saw

I have set up the grinding machine which was very easy. I have not used it yet but will be soon. I have taken it apart to set up the saw attachment which was also easy and have used that and am loving it.
