Review: Quality bits and solid durable case - Although I already had a range of flat bits I bought this set to cover the sizes I didn’t have and more importantly for the case as I find it a pain to have to sort through a bunch of bits looking for the correct size. The bits are of excellent quality and sharpness as most reviews have indicated. The shafts are thick and strong with no danger of bending, even if given some abuse. The case I received was black and yellow rather than yellow and black (see pic), but apart from that identical to the product images. The case comes with some thin clear plastic retainers which support the bits at their tip as well as some black point protectors (which are just a lose fit). I think these are both just transport packaging as with them in place it is awkward to remove the bits so I dispensed with both and they still stay firmly in position during transit from site to site and are much easier to remove. There are several extra positions within the case for extra bits which I will no doubt fill at some point. All together a very good buy at a reasonable price considering the quality. Review: Dewalt quality - This is a little bit like re-inventing the wheel. I'm guessing that Dewalt R&D Dpt looked at a spade drill and wondered how they could improve it. And indeed they have. The shank is thicker (as a lot have stated) removing the risk of twisting the bit. All spade drills are made with a front rake clearance to enable the bit to cut. Dewalt have gone better by adding a top rake angle as well. The final touch is a slight chamfer on the corner of the bit. Absolutely fantastic product to use and comes with a very practical and strong case. They work like a dream and if I ever need to replace them it will be with the very same. If I was to be very picky and find fault it would be to say that they are a little difficult to get in and out of the case but it is such a small point and I still have to give it 5 stars. ## Features - For fast and accurate results in hardwood, softwood, lumber, and wood with nails - Ideal for door locks, mortising, electrical and plumbing work - Extra thick and robust steel shank for outstanding durability. 1/4" shank ensures easy and slip-proof clamping - Flat Bits: 12, 16, 18, 20, 22, 25, 28 and 32mm - Supplied in a tough case ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0035YP2HY | | Best Sellers Rank | 57,204 in DIY & Tools ( See Top 100 in DIY & Tools ) 34 in Spade Bits | | Brand | DEWALT | | Customer Reviews | 4.7 4.7 out of 5 stars (3,880) | | Cutting Angle String | 6E+1 Degrees | | Cutting Diameter | 32 Millimetres | | EU Spare Part Availability Duration | 1 Years | | Finish Types | Steel | | Global Trade Identification Number | 05035048073292 | | Included Components | DT7943B Extreme Flat Bit Set, 8 Piece | | Item Dimensions | 28 x 29 x 4.5 centimetres | | Item Type Name | DT7943B Extreme Flat Bit Set, 8 Piece | | Item Weight | 190 g | | Manufacturer | DEWALT | | Material | Alloy Steel | | Model Number | DT7943B-QZ | | Number of Flutes | 2 | | Point Style | Brad Point | | Shank Type | Straight | | Surface Recommendation | Wood | | Tool Flute Type | Straight | | UPC | 604310246198 | | Unit Count | 1.0 Count | ## Product Details - **Cutting angle string:** 6E+1 Degrees - **Cutting diameter:** 32 Millimetres - **Finish type:** Steel - **Material:** Alloy Steel - **Shank type:** Straight ## Images ![8 Piece Extreme Flatbit Set, DT7943B-QZ - Image 1](https://m.media-amazon.com/images/I/91JGYLelKjL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality bits and solid durable case *by H***Y on 30 May 2016* Although I already had a range of flat bits I bought this set to cover the sizes I didn’t have and more importantly for the case as I find it a pain to have to sort through a bunch of bits looking for the correct size.

These and their Brad Points are the best woodworking bits I've ever used. Very happy with the quality of the construction, these are incredibly strong bits, no flexing at all. Hex shanks are lovely. Tip protectors are a nice touch. The box is good, but I would have preferred bespoke inner mounts, these bits do deserve them. In use they cut through all wood types with equal ease. No splinters, clean cuts. Lovely. I agree with everyone else over these. Very highly recommended, if you're in the market for some flatbits then look no further. ## Frequently Bought Together - DEWALT 8 Piece Extreme Flatbit Set, DT7943B-QZ - DEWALT Extreme Flat Wood Drill Bit 9 Piece Set, Impact Rated, DT70751-QZ - DEWALT 19PC HSS Black and Gold Drill Set --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/48028838-8-piece-extreme-flatbit-set-dt7943b-qz](https://www.desertcart.co.th/products/48028838-8-piece-extreme-flatbit-set-dt7943b-qz) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-22*
