Fast Drilling TT48 Core Drill Bits And Realing Shell With Long Life And High Performanc
1. FEATURES:
High diamond concentration High penetration rate
Long life when used correctly Factory price
2. RECOMMENDED FOR:
Coring in medium to ultra hard formations from abrasive to fine competent, using water or mud flush.
3. IMPREGNATED DIAMOND CORE BITS OVERVIEW:
3.1 IMPREGNATED DIAMOND CORE BITS:
The impregnated diamond bits are manufactured using high quality raw materials for optimum drilling performance. These impregnated bits present a metallic layer impregnated of diamonds on its cutting face. These impregnated bits are made by mixing fine diamonds with a metallic powder called matrix. The mixture is then subjected to heat treatment assuring the metallurgical bond of the matrix on the steel blank. To maintain optimal performance during entire bit life, it is important that matrix wear is synchronized with the diamond wear to ensure exposure of new diamonds with sharp edges.
3.2 CROWN HEIGHT:
Changsha Drilling currently offers 4 standard impreg depths of 6mm,9mm, 12mm and 14mm, that are used in all geotechnical & mining applications. The longer crown heights provide improved bit stability and reduce vibrations, enhancing bit performance and life.
3.3 CROWN PROFILE:
Our clients can avail from us a wide range of impregnated bits that includes W, FLAT, SEMI-ROUND, and MULTI-STEP, in order to superior coring performance, longer bit life, reducing costs and improving production.
3.4 WATERWAY OPTION:
There are available in 4 different waterway configurations includes of STANDARD, FACE DISCHARGE, TURBO, and TAPERED.
Also available in WIDE waterway configurations .
