Best Drill Bits for Metal for 2024 - hss vs carbide
Equipped with a radar cross-section and visual and Infrared augmentation system necessary for weapon practice, it also features a laptop-based Ground Control System that enables aircraft integration, pre-flight checks, data recording during the flight, replay after the flight, and post-flight analysis.
Getting dadoes cut to the exact right width is the problem, and here's the solution. Or at least the solution that I prefer. ...

The trials were carried out with four different mission objectives, utilising a single booster designed by the Advanced Systems Laboratory, Hyderabad, to provide reduced launch acceleration.
Here’s a close up of the tip after “sharpening”. Not perfect, but it didn’t have any problem drilling through the 1/4″ thick hardened steel chisel I used for the test:

Judging from the comments I have received on a few of my videos (and another from a few years ago on a forum I participated in), there is a fairly widespread misunderstanding of what oil…
One is a regular, cheap masonry bit that I’m pretty sure I’ve never used. The second is a high quality SDS bit that I cut the thickened shank off of to use in a regular drill. The SDS bit has been used many times and is very dull.
Four flight trials of the High-speed Expendable Aerial Target (HEAT) 'ABHYAS' were successfully conducted by the Defence Research and Development Organisation (DRDO) from the Integrated Test Range in Odisha's Chandipur.

It probably doesn't happen often, but occasionally you might have to clamp something together that even you longest clamp won't reach. While building a new storage cabinet for my shop, I had add onto the…
Throughout the flight trials, various parameters such as required endurance, speed, manoeuvrability, altitude, and range were successfully validated. The trials were conducted between January 30 and February 2.

In conclusion I’ll say that it definitely works, and possibly a lot better than demonstrated here if the right grinding wheel is used to get a cleaner cutting edge. Also starting with a new, unused bit will make a difference. The bits I used were worn out and used in a hammer drill, which would make the carbide more prone to breaking.

The flights have been designed by DRDO’s Aeronautical Development Establishment (ADE) which offers a realistic threat scenario for the practice of weapon systems. It is engineered for autonomous flying with the assistance of an autopilot developed indigenously by the ADE.
This blade is not ideal for sharpening carbide, as the diamond particles are a bit too large to do a good job. It’s all that I have right now and I figured it will be good enough for a quick test. Since I would like to make a circular saw sharpening jig at some time in the future, I will be getting a proper grinding wheel for that purpose, and that can be used for this as well.
The objectives, such as the safe release of the booster, launcher clearance, and attaining the required end-of-launch velocity, were achieved. Throughout the flight trials, various parameters such as required endurance, speed, manoeuvrability, altitude, and range were successfully validated.
The second, unfinished hole is from the SDS bit. I stopped after it was clear that it wasn’t going to finish and I believe I could have done a better job of sharpening that one. Still, it did make it more than half way through the chisel.
The systems recently tested were also realised through manufacturing units of Hindustan Aeronautics Limited (HAL) and Larsen & Toubro (L&T) Defence.
This was actually a tip that I got from a comment on my “Making A Knife” video that I dismissed as something that wouldn’t work. I normally try to have a more open mind, but thought that there’s no way you could get a masonry bit sharp enough to drill into hardened steel. Well, I stand corrected and it’s a good example of how we can discount an idea based on what we think is correct, when it’s always better to take the time and try it first.
