IMPAKT Top Hammer Bits

RACEWAY TECHNOLOGY

After development and global 3rd-party testing, the IMPAKT design innovation has been proven to actively clear cuttings from the entire cutting face. With flushing speeds increased by 25%, the resulting penetration rate has been improved by an average of 18%.

RACEWAY SCIENCE OF FLUSHING

The IMPAKT face design is based on reducing the residence time of cuttings at the face. Raceway flushing quickly clears cuttings from the entire bit face for a lower Cuttings Residence Time (CRT) and more effective energy utilization.

TRADITIONAL FACE DESIGNS

IMPAKT FACE DESIGN

Traditional bits have a center ‘deadpool’

Standard designs focus on clearing the gauge

Opposing pressure causes stagnation of cuttings on the face

This ‘deadpool’ creates a cushion against effective energy transfer

Raceway ensures full-face flushing

Raceway design clears both the face and the gauge

Pressure and flow accelerate cutting removal

All buttons in contact with fresh rock maximize efficiency in each strike

BT Series Hammers

Marketing — Mon, 08 Nov 2021 22:40:09 +0000

BT Series Hammers

Great balance of simplicity and performance:

Most productive piston concept (or “Piston concept maximized penetration rate”)

Strongest QL/QLX 12-spline shanks, to maximize longevity/reliability/durability

100% tubeless, no troublesome foot-valves.

Light and simple, easy to handle and support

Maximum wear life, hard-faced drive chucks and back reaming buttons

Download

1. TOP SUB
Back reaming buttons protect the top sub against wear when pulling out of the hole.

2. SOLID PISTON
Most productive piston concept, maximizing penetration rates.

3. GUIDE SLEEVE
Serves the same function as the plastic foot valve, but is a much more reliable solution.

4. DRIVE CHUCK
Hard facing protects the drive chuck and extends the life of the hammer.

• Flat for easy sharpening and maintenance.

Diameters range from 110 to 190 mm (4.3 to 7.5 inches)

Features

Industry Preferred Shanks

QL/QLX 12-spline shanks. Make the switch to the most solid and wear-resistant in the market.

Tubeless - No Foot Valves

Bits for the BT hammers 100% without foot valves. Maximizes reliability by eliminating a plastic weakness. 5” and 6” bits provided with an optional foot valve to fit traditional tubed hammers.

Premium Carbide Inserts

Fine-tuned hardness and toughness to increase carbide life. Supports multiple re-sharpenings to amplify bit life. Choose between ballistic and hemispherical inserts.

DRIFTMASTER

Optimized strength, fatigue resistance, and wear life.

DRIFTMASTER THREADS REDUCE STRESS FOR EXTENDED LIFE

The tapered thread profile provides a larger cross-section at the high-stress location (more steel where it is needed)

The unique thread profile further reduces the thread root stress compared to standard designs.

A +25% reduction in applied stress leads to an exponential increase in the fatigue life offered by DM28 and DM35.

Shanks

Made from high-quality steel, Boart Longyear shanks are manufactured to provide optimal wear resistance, strength, and toughness to provide maximum energy transfer from the hammer to the drill string.

We carry a wide variety of products that provide compatibility with most standard hydraulic, pneumatic hammers.

Custom products are available upon request.

Male Shank Adapters

Generally better suited for drifting, tunneling and extension applications where high bending stresses are present.

Female Shank Adapters

Used when the drilling space is limited and the total feed length is important (i.e., underground roof bolting).

Accessories

Full range of accessories are available to maintain a high level of productivity:

Bit adapters
Guide adapters
Split set drivers
Nut drivers
Adapter couplings
Recovery tools

Surface Rods

Marketing — Mon, 22 May 2017 19:38:52 +0000

Surface Rods

Male/Female Rods

The male‐female design configuration eliminates the need for a separate coupling resulting in faster additions and removals to the drill string, and reduced hole deviation due to fewer threaded connections.

End forms are fully heat treated to provide:

Market‐leading wear resistance during drilling and coupling or uncoupling.
Reduced galling, chipping and surface damage.

Straight Hole Drilling

Boart Longyear’s EL threads and mid‐body diameters up to 70 mm combine to provide:

Straighter holes—resulting in fewer holes required, more consistent fragmentation, increased efficiency, and reduced operational costs.

Hole diameters up to 152 mm (6”)
Increased use of the power available from the latest generation of top hammer drills and efficient energy transfer for improved penetration rates.

Easier uncoupling resulting in extended drill string life, reduced time per hole and lower drill maintenance.

Features

1. END THREAD FORMS
Rods are available in male/female or male/male

2. THREAD HEAT TREATING
Male and female threads are heat treated to provide high wear resistance and durability

3. PREMIUM MID‐BODY STEEL
Designed for air flushing and optimal rod compliance, the mid body’s structure is strong and durable with efficient energy transfer.

4. THREAD FORMS AND SIZES
A wide range of thread types and sizes are available to meet project specific needs.
