Carbide tipped drill bits - Locksmith Blog
Topic: Reviews

With lock manufacturers being pressured into producing even more impenetrable locks our lives as locksmiths are getting trickier by the day.

Im not a big fan of pushing high security locks onto the domestic customers;

for one: It makes my life as a locksmith much more stressful in the event of a lockout.

two: Burglars rarely attmept to open a lock anyway.

So the last few months iv come across quite a few nasty locks that have felt the wrath of the rotary pick... and then laughed at me while they resisted to the last slither of metal holding them strong.

As most locksmiths will know; drilling a lock can go terribly wrong!
(Thats deffo not one of mine btw! HaHa)

Throw in torrential rain or a poorly lit alleyway and you are guarantee'd a headache.

So lets get to the point.

Good hardplate carbide tipped drills are relatively expensive!
Faced witha good BS rated cylinder and a spot of bad luck could see you using 3 bits when drilling at the traditional sheer line point.

Iv been testing a few different brands of carbide drill to see how they fare in the locksmiths world.

All drills have been tested on locks containing two or more hardened anti-drill pins plus one or more stainless key pins.

SKS budget drill:

These are priced in at £2-3 plus VAT for a useable size.

Poor penetration against hardened pins

Struggle against stainless key pins.

Budget Duffells drill:

Priced between £1.30 and £2.20 plus VAT for a useable size.

Reasonble penetration against hardened and stainless pins.

Cutting edge continues down the drill bit for widening holes


Souber Tungsten Carbide bits:

More expensive range at £3-4 plus vat for a useable size.

Reasonable penetration against hardened and stainless pins.

Last slightly longer that the other budget ranges.

Alpen Reds

Much stronger than other budget ranges with the same strength as the Souber bits.

Price is very reasonable and these are now stocked by all the major trade suppliers.
