First using quarrying dedicated drill holes, remove residual powder of hole3. Next upside down the big side of 2 wedges (flat to flat),and put it into hole4. Then upside down the small side of central wedge between 2 wedges , and finally using the hammer split stone Review: These worked wonderfully splitting concrete. I had previously tried using them on a large granite boulder and it seems to split off in layers layers. For that Dexpan worked better but takes a couple days. 1. Snap some lines across whatever you want to split. 2. Mark up where you want the wedges and spread them evenly across what you want to split. I placed one ~ every 6inches. 3. Hammer drill 9/16" holes deeper than the wedges, as it's hard to clear out all the dust and you will lose depth. 4. Place the wedges in the holes. Use a small handheld sledge and give each wedge 2 taps, going down the line, the 2 taps on the way back. Go back and forth until the concrete starts to split. It can take a little time for the hairline crack to start to show. Keep going until the concrete spreads and you get a gap...but don't pound the wedge to the surface. **Don't drill 5/8 in holes. You could but the wedges may go to low. 1/2" holes could work on thinner concrete, but are a bit too small and you may bend a wedge. Review: I wish I knew about these sooner. I’ve used them a bunch since purchasing. Still holding up. ## Features - Size: Diameter 5/8"(16 mm), Length 4-2/5"(110 mm) - Material: High Hardness Steel - Suitable for Splitting the hard stone，rock，granite，concrete - High-quality steel, heat treatment process, High hardness, toughness, low cost, cost, versatility, easy to use - Please keep it out of reach of children and safety first ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07D65J1RN | | ASIN | B07D65J1RN | | Batteries Included? | No | | Batteries Required? | No | | Customer Reviews | 4.5 4.5 out of 5 stars (88) | | Customer reviews | 4.5 4.5 out of 5 stars (88) | | Date First Available | 18 August 2018 | | Date First Available | 18 August 2018 | | Finish | Uncoated | | Is Discontinued By Manufacturer | No | | Item Weight | 1.14 Kilograms | | Item model number | G20240103-3 | | Item model number | G20240103-3 | | Manufacturer | FLK Tech | | Manufacturer | FLK Tech | | Material | steel | | Part number | 8 | | Product Dimensions | 20 x 17 x 5 cm; 1.14 kg | | Product Dimensions | 20 x 17 x 5 cm; 1.14 kg | ## Product Details - **Cutting angle string:** 90 Degrees - **Cutting diameter:** 0.63 Inches - **Finish type:** Uncoated - **Material:** steel - **Shank type:** Straight ## Images ![FLK Tech 8 SET 5/8" Plug Wedges and Feather Shims Concrete Rock Stone Splitter Hand Tools 16mm - Image 1](https://m.media-amazon.com/images/I/71CAsn0EP9L.jpg) ![FLK Tech 8 SET 5/8" Plug Wedges and Feather Shims Concrete Rock Stone Splitter Hand Tools 16mm - Image 2](https://m.media-amazon.com/images/I/81xInuEogQL.jpg) ![FLK Tech 8 SET 5/8" Plug Wedges and Feather Shims Concrete Rock Stone Splitter Hand Tools 16mm - Image 3](https://m.media-amazon.com/images/I/810GdUXGQ0L.jpg) ![FLK Tech 8 SET 5/8" Plug Wedges and Feather Shims Concrete Rock Stone Splitter Hand Tools 16mm - Image 4](https://m.media-amazon.com/images/I/71aZ6KM6XoL.jpg) ![FLK Tech 8 SET 5/8" Plug Wedges and Feather Shims Concrete Rock Stone Splitter Hand Tools 16mm - Image 5](https://m.media-amazon.com/images/I/81Q4XDeBVxL.jpg) ## Questions & Answers **Q: what size should the drilled starter holes be?
