Manufactured at Lotus ISO 9001:2015 certified facility . Lotus rock roller bits are indeed the leading cutting edge of drilling technology offering high performance drill bits. Lotus bits are custom made for highly specific applications that include on shore and off shore oil exploration, blast hole drilling for mining, and water-well drilling. Lotus bits are produced with conformity to the highest standards, and are certified to carry the prestigious American Petroleum Institute (API) Monogram. As a leader in rock roller bits, Lotus employs state-of-the-art manufacturing and quality control processes to ensure maximum drilling efficiency and a longer bit life. Lotus bits are manufactured to withstand extreme drilling pressures that test their endurance to the limits. Lotus rock roller bits take the top position when optimum drilling cost is a priority, something which all of our customers will wholeheartedly vouch for.


Our technical team will work with you to determine the right bit for your application.

  • Careful consideration of rock compressive strength and BHA configuration.
  • Expert analysis of cutting structure design to help you maximize your intervals.
  • Our team will follow up with you to ensure complete satisfaction with the product.


TCI Stands for Tungsten Carbide
Insert. These Tricones are designed
for soft to very hard formations
depending on the style and quality of
the carbides on the drill bit, sealed
bearing TCI Tricone bit or without
gauge protection.

Manufactured as per API Standards and specifications with superior quality steel, advanced technologies, designed for use with compressed air or fluid circulation systems. Regular and Jet circulation available.

1.Center Jet

Centre Jet is mounted at the centre of the bit. They are effectively used to prevent bit bailing in sticky formations.Available both in convergent and
diffuser type

3.Gauge Protection Inserts

These are profiled inserts pressed in the outer edge of the gauge face. These protect the gauge of the bit in abrasive formations. Gauge protection inserts are standard on TCI Bits.

5. Air Circulation

This is available in milled tooth & TCI Bits to drill with air as a circulation media. Some part of air flow is utilized to clean & cool the bearings.

2.Mini Extended Nozzle

They are used to increase rate of penetration in soft to medium-soft formations. These nozzles keep the jet flow closer to the hole bottom. When the bit has miniextended nozzles, ensure that the bit does not rest against the noz z les during makeup or breakout of bit.

4. Extended Shirt Tail & Ball Plug Protection

Tungsten Carbide inserts are pressed into the shirt tall area to provide extra protection of ball plug and shirt tail.

6.Body & Shirt Tail Protection

Additional protection to the leg body & shirt tail whilst drilling in abrasive formations & in the directional drilling
