Mini Hand Drill Set with 20pcs Twist Bits 0.3-1.6mm, Linkstyle HSS Spiral Pin Vise Bit Hand Manual Push Drill Chuck for Delicate Manual Work, Electronic and Model Making, Drilling Holes, Wood Working

The actual drill part is a bit too flimsy to useful, but the selection of very slim bits is well worth the money on their own. I'd buy this just for the very fine bits.

Just what I needed for hobby making, but the tips have not been sharpened properly, and I need to start the hole off with a bradawl

Perfect hobby drill set for model making. Used to make various holes from 0.3 to 1mm. Drill clean holes and hasn’t caused any damage to models. Drill bits are sharp but could be more durable. This can easily be upgraded with other drill bits.Would be helpful to have a centre punch to start the drilling.

Well worth the money. Don’t expect to use it much, so should be fine.

This review is for the Linkstyle Mini Hand Drill Set with 20 bits (0.3mm to 1.6mm)that includes the pin vice with the Archimedes screw mechanism.The biggest issue with this drill set is (as many others have reported) the inclusion of drills that have never been ground to a cutting point - they have missed the final manufacturing step of creating the angled tip and cutting edges. In my case only the 5 largest drills had any attempt at a ground cutting tip - all the drills smaller than 1mm were completely unfinished with a square cut end and no cutting edges. This problem is either due to indifference about the quality of the product or a serious deficiency in quality control. Obviously I have no way to determine what percentage of supplied drill sets are being supplied in this condition - but it appears this is not just a one off poor set by the number of reports in the feedback.For the price I couldn't be bothered to return them - and chose to grind the required point and cutting edges on all the drill bits myself (not an easy task bearing in mind the very small size of the bits). It is unclear at this stage how long the drill bits will retain a cutting edge - but I suspect the quality of the steel is unlikely to be the best. These drill bits are only recommended for drilling into softer material so I doubt they are actually HSS rated as claimed.The second problem is that quoted drill bit sizes (for those smaller than 1mm) are at best "flexible" and at worst just incorrect. Most people will not have the equipment to accurately measure the diameter of drill bits smaller than 1mm - but a few other purchasers have also noted sizing issues. The 5 smallest drill bits are all essentially 0.5mm - so the 4 smallest sizes are incorrect - as they are quoted as 0.3, 0.35, 0.4, 0.45mm. The next largest bits should be 0.55, 0.6, 0.65mm - but they are all 0.584mm. And from there I have 3 pairs of bits measured as 0.711mm, 0.787mm, 0.889 rather than the quoted 0.7, 0.75, 0.8, 0.85, 0.9, 0.95mm. This appears to be a deliberate simplification of the supplied sizes to reduce the production costs - with only 12 sizes supplied rather than 20 different sizes. So if you want an accurate set of miniature drill bits this is not the product for you - even if you were prepared to grind cutting points on the majority of the drill bits before they can be used.

I've given this 3 stars as only half of the product is of any use. As others have mentioned already the set of steel drill bits (black) have no point and are flat-bottomed. I tried to drill a 1.0mm hole in a piece of peg wood but the bit wouldn't even start the hole, completely useless. I inspected most of the bits under a scope and all the ones I looked at were the same so I stopped wasting my time. However, the PCB bits worked fine and had no problem drilling the small hole with the help of a Dremel , and these did have a point. The vice came in useful to hole the peg wood while drilling so that gets a thumbs up. The pin vice, although not used yet, looks okay and the jaws close completely tight. Overall, I'm quite satisfied but also a bit disappointed that the majority of drill bits are useless and the manufacturer should look into this.

It works on brick

Brilliant little tool
