DIMATEC INC. INTRODUCES S-SERIES DIAMOND IMPREGNATED CORE BIT PRODUCT RANGE

Dimatec Inc., a Canadian owned, ISO 9001:2008 manufacturer of diamond tools used in the mineral exploration sector has completed development of a new series of diamond impregnated core bits called the 'S-Series'.

Dimatec’s S-Series range of products are intended to complement the existing D-Series and HR-Series product ranges that have gained widespread acceptance around the world. The D-Series line of products are well established as a good, general purpose range of bits while the HR-Series are known to provide superior high production rates without the need for high bit loads. The newly developed S-Series line of products has been developed to offer the end user similar cutting performance to the existing HR-Series bits while offering better overall bit life when used on higher powered drilling equipment.

Field testing of the S-Series products over the last 12 months has resulted in 20%+ improved bit life combined with smooth cutting performance and good penetration rates in medium to hard, fine grained formations when compared with corresponding HR-Series products.

The S-Series products have been designed to provide numerous operating “sweet spots” in which the bit will cut smoothly and freely without the driller having to constantly adjust thrust pressures, rotational speeds, and/or circulation flush rates in order to maintain an acceptable level of performance.

S3 Matrix Characteristics

  • The most wear resistant matrix type offered by Dimatec.
  • Designed for use on high-powered drills in formations such as Sandstone where the conditions are often broken and highly abrasive.
  • Not effective in hard, fine-grained formations.
  • This matrix requires highly abrasive conditions within the formation being drilled in order to maintain sharpness and high rates of penetration.

S6 Matrix Characteristics

  • Designed for use on high-powered drills in hard, abrasive and broken formations with mixtures of softer and harder rock.
  • Provides good rates of penetration while achieving good bit life in blended sedimentary and metamorphic formations.
  • Where small slips of harder rock are present in abrasive rock of medium hardness, the S6 Matrix will often cut the harder sections without increasing bit load or torque.

S7 and S8 Matrix Characteristics

  • Highly durable matrices that can withstand higher bit loads (weight-on-bit).
  • Provides above average rates of penetration in medium-soft to medium-hard rock types that possess a visible grain structure.
  • Well suited for use in formations with a hardness in the Mohs 5 to 7 range.
  • The S8 Matrix is more free cutting and will often provide better rates of penetration than the S7.
  • The S7 Matrix will provide better overall bit life than the S8 when used in similar conditions and under similar drilling parameters.
  • The S7 Matrix generally requires higher bit loads (weight-on-bit) and is not recommended for use on light-weight and/or low-powered drills.

S9 Matrix Characteristics

  • The S9 Matrix has an exceptionally broad range of application in a variety of softer abrasive to harder non-abrasive rock types.
  • Designed for use on high-powered drills.
  • Readily self-sharpens and provides good bit life as well as consistently high penetration rates, even when used in changing formations.

S10 Matrix Characteristics

  • Suitable for use in a broad range of rock types with coarse to fine grain structures in the Mohs 5 to 7+ hardness range.
  • Although the S10 Matrix can withstand higher bit loads, it can also provide good rates of penetration at lower bit loads without the need for frequent driller intervention to sharpen the bit.

S11 Matrix Characteristics

  • The S11 Matrix has an exceptionally broad range of application in a variety of harder formations with either coarse or fine grain structures.
  • Designed for use on high-powered drills.
  • Readily self-sharpens and provides good bit life as well as consistently high penetration rates, even when used in changing formations.

S12 Matrix Characteristics

  • The S12 Matrix has an exceptionally broad range of application in a variety of harder formations with either coarse or fine grain structures.
  • Designed for use on high-powered drilling equipment to drill hard to very hard formations that possess fine to very fine grain structures with a hardness in the Mohs 6 to 7.5+ range.
  • The S12 Matrix will provide steady penetration under higher bit loads in very hard, fine grained formations while still providing good overall bit life.
