MaxLife total hardfacing reduces exposed steel. Our steel tooth bits with this application-specific technology last longer, drill deeper, and stay sharper for superior ROP. In high-wear applications, MaxLife increases

• durability
• abrasion resistance
• cutting structure protection
• seal protection
• erosion resistance.

Reduce tooth wear
An additional 33% more hardfacing on the tooth crest compared with our XLX technology resists wear. The remaining tooth geometry has 25% more hardfacing. With this added protection, you can run our bits multiple times.

Use fewer bits
A formation of interbedded sand and sandstone in southeast Mexico was causing excessive cutting structure wear. The operator let us test our 17-1/2" MXL-1X with MaxLife hardfacing and our standard MX-1 in two offset wells.

One of the three MXL-1X bits set a field record for the longest run with 1.01 million total bit revolutions and 3,356 ft [1,023 m] drilled. The bit was pulled seal-effective. Compared with the six MX-1 bits used in the field’s first well, the MXL-1X with MaxLife total hardfacing in the second well enabled the operator to

• use 50% fewer steel tooth bits
• drill an average 70% more footage
• achieve, on average, 49% greater ROP
• complete, on average, 54% more total bit re
