Different Types Of Drill Bits And What They Are Used For - wood drill bit vs masonry drill bit

This is Wayne Winton with Tri County Locksmith Service. I have used the TTP-HARD-drills and personally feel they are some of the highest quality drill bits I have ever used. They work well on a variety of  steels from hardened spring steel to brass and aluminium, all with fast cutting speed and easy drill point starting. They are far superior to the average drill bits that can be purchased at the local hardware store. They have put much time and research into their product and it shows in pure performance. These drill bits are in my service truck and will be for a long time.

Just to let everyone know these drill bits are BRILLIANT, it is the first time I have ever worked with metal and was using Bosch titanium bits, managed 3 holes with 3mm drill bits. Then I ordered TTP bits and they were like a hot knife through butter. I was drilling 1cm hard steel and the job was so easy. Highly recommended, don’t buy expensive imitations.

1/4 end mill(s) are the most popular size of end mill sold in the metal cutting industry today.  They are a versatile tool that can be used for a variety of tasks, including milling, drilling,  deburring, and chamferring.  They are available in several standard end mill geometries with general purpose and high performance uses.  They come with multiple number of flutes and flute lengths.  The most common material is solid carbide with multiple PVD coating options.  We also have special geometries for aluminum and roughing end mills.

We sent our drill bits to renowned locksmith Wayne Winton from Tri-County Locksmiths in Colorado to see what he thought of them. Here are just 2  of the videos he posted on Youtube.

I broke two stainless bolts in the head of my ex-US Army jeep engine which defied left hand bits, quality HSS right hand bits, gas and brute force. They were just an inch long and eventually we got a small pilot hole and a pile of blunt drills. I read that cobalt drills were worth trying, found the TTP site, saw the videos and ordered two of two sizes (in case they got blunt?). A decent-ish corded drill and a single TTP just sliced through both bolts using plenty of oil and low speed as advised in the vid and info leaflet. After a wipe with a rag the drills went in the tool box – though I couldn’t tell which was the used one and which was unused. It sounds corny but I should have got the TTP drills earlier and saved a lot of time and hassle.

I was very happy with my purchase of the tough drill bits , they allowed me to drill out some broken off tensile bolts from a 25 year old motorbike cylinder head , failure in this would have meant finding a new head or abandoning the project

I had already wasted a mix of various ten HSS, Tungsten and Titanium coated drills without even successfully drilling one hole and was running out of ideas. After trawling the internet I came across the TTP drills and was so impressed with the video I ordered a selection of sizes to try them out. What a difference! A firm pressure and some jiggling with the drill speed soon resulted in the drilling of all the holes with one drill and with the same curl of swarf seen on the video. The other drills produced dust, if I was lucky.

Reviews from some of our clients who rank TTP HARD drills as the best cobalt drill bits for drilling harder metals including stainless steel.

Hello there….I just thought I’d drop you a line commending your products. The 6,5,4 and 3 mm drill bits work a treat on my stainless steel cycle rack. Initially I ran the drills too fast and I didn’t use enough pressure which resulted in poor performance, particularly on the larger drill sizes. I quickly learned that slowing the drill down and increasing drill pressure whilst ensuring enough cutting grease had been applied enhanced the drilling performance immensely. It used to frighten me when drilling stainless steel. NOT ANY MORE! Well done your Company!

They are fabulous. I still haven’t had the time to use them for their actual intended purpose – drilling out exhaust manifold studs, but I did try them out on a couple of bolts to see how they did and was very impressed! Told a bunch of my friends about them. Hoping to get a joint order together. I want more sizes or one of the sets!

Best drill bits I’ve ever used by far, I purchased several different cobalt bits trying to drill into a broken cylinder head bolt to extract it and not one would do more then scratch the hardened head bolt. After hours of trying to drill into the broken bolt I decided to go online and find a different type of bit, after watching many videos about these bits I decided to purchase a full set with their ‘in house lubricant’ as well. Within 10 mins I had the broken bolt drilled and extracted, I’ve never seen a bit cut hardened steel that effortlessly before, I am a life time customer from here on out, worth every penny. Thank you

TTP may sell tough products but I found them anything but tough to deal with, communications were excellent and the drills arrived on time and well packaged. I would deal with them again without hesitation and can highly recommend their products and service. Thanks TTP.

They are amazing. Didn’t believe the hype, but it appears to be true. I am a locksmith and drill hard plate on safes. They really tore into it.
