Product Overview
The 15-Piece Precision Setup Block & Height Gauge Set is an essential tool for any workshop where repeatable precision matters. Whether you’re setting table saw blade height, router bit depth, fence alignment, or drill press stops, these CNC-machined aluminum blocks deliver the accuracy you need – without the frustration of tape measures, combination squares, or improvised spacers.
Each block is precision-ground from solid 6061 aluminum alloy and finished with a black anodized coating that resists wear and prevents marring of your tool surfaces[reference:10]. The laser-engraved size markings are permanent and easy to read, even in poor lighting[reference:11]. Stack multiple blocks to create custom heights – the 15-piece set provides over 100 possible measurement combinations[reference:12].
This set replaces the need for separate setup bars, feeler gauges, and improvised spacers. It’s the go-to tool for professional woodworkers, machinists, and equipment repair technicians who demand fast, repeatable setups without compromise.
💡 Pro Tip – The Stacking Method: For heights that fall between the individual block sizes, stack two or more blocks together. Ensure the mating faces are clean and free of debris – even a 0.001″ layer of sawdust will throw off your setup. Use the included storage case to keep blocks organized and protected from shop contaminants. For critical setups, always verify your stacked height with a caliper before locking down your fence or blade.
Diagnostic & Fitment – When to Use Setup Blocks
Specification Comparison
| Specification | Cheap / Generic Setup Blocks | FixPartHub Precision Replacement ✅ |
|---|---|---|
| Accuracy | ±0.005″ or worse – inconsistent setups | ±0.001″ – CNC-machined precision[reference:16] |
| Material | Cast or low-grade aluminum – prone to warping | Solid 6061 aluminum – dimensionally stable |
| Finish | Bare aluminum – oxidizes, marks tools | Black anodized – non-marring, corrosion-resistant[reference:17] |
| Size Markings | Painted or stamped – wears off | Laser-engraved – permanent[reference:18] |
| Number of Blocks | 10 or fewer – limited combinations | 15 blocks – 100+ measurement combinations[reference:19] |
Setup & Usage Workflow
Compatibility – Sizes Included
All blocks are 3 inches in length except the 1x2x3″ block[reference:20][reference:21].
Diagnostic Q&A
❓ Q: How accurate are these setup blocks?
A: Each block is CNC-machined to within 0.001″ (0.025mm) of its stated dimension[reference:22]. This level of precision is sufficient for woodworking setups, router table adjustments, and most drill press operations. For reference, a human hair is approximately 0.003″ – these blocks are three times more precise than that.
❓ Q: Can I use these blocks for setting table saw blade height?
A: Absolutely. Place the appropriate block(s) against the table surface next to the blade. Raise the blade until it just touches the top of the block. This gives you an exact blade height setting – eliminating the guesswork of using a combination square or ruler[reference:23].
❓ Q: What’s the advantage of setup blocks over using a tape measure or ruler?
A: Speed and repeatability. A tape measure or ruler requires you to read a scale, align your eye, and adjust – all with room for parallax error. Setup blocks are a physical, tactile reference – you simply place the block and adjust until contact is made. No reading, no interpretation, no error[reference:24].
❓ Q: Can I stack multiple blocks together?
A: Yes. Stacking blocks allows you to achieve virtually any height or depth measurement. The 15-piece set provides over 100 possible measurement combinations[reference:25]. Always ensure the mating faces are clean and free from debris before stacking – even a small particle of sawdust will affect accuracy.
Safety & Maintenance Notes
- 🔴 Always disconnect power from your tool before making any setup adjustments with the blocks.
- 🧤 Keep blocks clean – wipe with a clean, dry cloth after each use. Sawdust and debris on the mating faces will affect accuracy.
- 🔧 Store in the provided case – protect blocks from impacts, moisture, and shop contaminants. The anodized finish is durable but not indestructible.
- 📐 Verify with a test cut – always make a test cut on scrap material before committing to your final workpiece.
- ✅ Inspect periodically – check for nicks, burrs, or wear on the block surfaces. Damaged blocks should be replaced.
A: The set includes 15 precision-ground blocks in the following sizes: 1/16″, 3/32″, 1/8″, 5/32″, 3/16″, 7/32″, 1/4″, 5/16″, 3/8″, 7/16″, 15/32″, 1/2″, 23/32″, 3/4″, and a 1x2x3″ block. All blocks except the 1x2x3″ are 3 inches in length.
A: Each block is CNC-machined to within 0.001″ (0.025mm) of its stated dimension. This level of precision ensures repeatable, accurate setups for table saws, routers, drill presses, and other shop equipment.
A: Yes. Setup blocks are ideal for setting router bit height, fence position, and depth stops. Place the appropriate block against the fence or bit and adjust until contact is made – then lock your setting
A: The blocks are precision-machined from solid 6061 aluminum alloy with a black anodized finish. The anodized coating provides corrosion resistance and prevents marring of your tool surfaces.
