The 17th is a 495-yard par-4 with a completely blind line off the tee. There is a sign with the hotel’s name — OLD COURSE HOTEL — that serves as an aiming point.

There are times when all you need is a specific bit size for single-use, and Bosch has one of the best deals for single cobalt bits. Bosch metal drill bits come in different sizes, starting at 1/8 of an inch. These drill bits for metal are durable and heat resistant and will do the work when it comes to drilling hard metals.

Cobalt (HSCO) includes between 5 and 8% cobalt in the base, making it an excellent option for drilling into harder steel and stainless steel.

“I’m like, ‘No, you hit it over the hotel,’ ’’ Thomas said he told her. “She’s like, ‘OK, but not really?’ I’m like, ‘Oh, no, really. You have to hit it over this hotel.’ ’’

For the best power drilling results for metal and steel, always choose a drill bit made of or has a percentage of cobalt. Cobalt is a material that offers better results in drilling through metal successfully. You can use one made of titanium for soft metal, and for light metal and aluminum, a black oxide coated-drill bit or a high-speed drill bit will do the job. And don’t forget to always use your metal drill bit at low speed for the best results.

Offering three different hole dimensions: 7/8, 1 1/8, and 1 3/8-inch and high capabilities to drill faster, this doubled-fluted step drill is a must-have for serious metal drillers. Though the price is a little high, it is well worth it for what it delivers.

There are many metal drill bit materials to choose from, including cobalt, high-speed steel, black oxide, titanium, etc. Often these drill bits for metal are sold as kits and are multi-purpose bits that you can use for various types of materials, including metal, wood and plastic. Usually, these bits are an excellent choice for soft metals and aluminum, but hard metals still may need a specialized drill bit.

“I hit one way right in [the Celebration of Champions] and I was out of bounds by like a yard,” McIlroy said. “Like I felt like I hit it right of the HOTEL and it was just out. So, you can really challenge that right side, but you have to have a lot of trust in your golf swing to do that. But once you get your tee shot away, it then opens up every hole location on that green.”

Tiger Woods, in 2000, famously avoided every one of the 112 bunkers for all four rounds when he won the first of his three British Opens.

One of the bunkers is a particular spot of bother, and it happens to be on No. 17, the most difficult hole on the Old Course. No. 17 also happens to be one of the quirkiest holes in major championship history, a hole on which players have to hit their tee shots over part of the Old Course Hotel.

The hole is so quirky that Justin Thomas made it a point to bring his fiancée, Jillian Wisniewski, to show her the hole and how bizarre it is.

In 2015, the last time the Open was played on the Old Course, No. 17 played 0.655 shots over par. There were more bogeys (217) than pars (203), and just nine birdies.

You can use these multi-purpose titanium drill bits with both regular and impact drills. They can cut through metals, wood and PVC easily. The set comes with 23 different drill bit sizes, and, thanks to these drill bits’ quad edge tip, they stay sharp longer, allowing you to perform more cuts.

“It’s very difficult,’’ Thomas said. “It’s the location of it and the placement of it and the way that the green sits and just how it swallows golf balls. I mean, anything that’s kind of around it that’s running, it’s just going to go right into it.

Rory McIlroy, playing in the Celebration of Champions exhibition featuring past Open champions on Monday, cut his tee shot right of the HOTEL sign and his ball ended in the bushes at the Jigger Inn, a famous pub overlooking the 17th hole.

When McIlroy was reminded that Woods never hit into a single bunker in 2000, he said: “It’s unbelievably impressive, especially when there’s so many tee shots here that are sort of half blind and little bunkers that are so well-placed. I think not going in a bunker for the whole week sort of just shows extreme control of your golf ball.’’

With 29 different highly-rated cobalt drill bits in all different sizes, this set’s price is well worth it for the number of bits you’ll get. You will be able to drill through any metal with these heat and abrasion-proof drill bits.
