Challenge Drill Bits

Challenge OEM drill bits feature a new alloy steel for an excellent balance of toughness, high-temperature strength, and wear resistance. This allows for:
- Extended bit life
- A sharper bit, through more drilling cycles
- Greater productivity with fewer changeovers

Plug-free Guarantee
If any uniquely-labeled Challenge bit gets plugged and breaks under normal usage, we will replace it free of charge. Insist on original Challenge drill bits!

Drill Bit Sizes

2" Capacity Drill Bits are used on all Challenge and Spinnit/Lassco Drills with the exception of the 1" table top machines.

2-1/2" Capacity Drill Bits are used in Challenge models EH-3A, EH-3C, MS-5 and MS-10A. These models will also accept 2" drill bits when the heads are adjusted down to the lower position. Generally if you own a 2-1/2" capacity drilling machine you will only purchase 2" bits if the size you require is not available in 2-1/2". There are nine additional size drill bits available in 2" which are not available in the 2-1/2" capacity size. Please remember to adjust your heads to the uppermost position before changing between a 2" and a 2-1/2" drill bits to prevent risk of breaking your bits. Please note that the old style EH-3 (110volt yellow machine) will only accept 2" capacity drill bits.

1" Drill Bits are only used in the smallest of Challenge and Spinnit/Lassco paper drills. Drill bits are not interchangeable between manufacturers, so please specify make and model when ordering 1" drill bits.
