TOP HAMMER DRILLING TOOLS
Customer Favorite
Sandvik rock tools for top hammer drilling are designed to transmit intensive impact energy into the rock with the least possible loss of energy. The result is good rock breakage, high penetration rates and high productivity. Along with optimal hole quality, great reliability and long service life, Sandvik tools deliver you the best possible blasting results, outstanding drill-steel economy and low overall operating cost.
TOP HAMMER DRILLING BITS
Sandvik's top hammer drilling bits are designed for extended wear life. In addition to this, you benefit from great versatility, higher penetration rates, straighter holes and longer bit life. Sandvik's exceptionally versatile series of threaded button bits, from 28-152 mm in diameter, are made from proprietary grade of cemented carbide throughout. Sandvik provides all the most efficient button shapes (spherical, semi-ballistic and conical) and the required skirt designs (regular or retract) in order to obtain the best bit for the rock formation in question.
TOP HAMMER RODS
Sandvik drill rods are manufactured from premium, high-strength, alloy steel and are available in either hexagonal and round configurations. Sandvik rods are developed and designed to give you straighter holes with less deviation and longer service life.
TOP HAMMER SHANK ADAPTERS
Sandvik manufacture premium quality shank adapters for most brands of rock drills. While every component in the drill string is crucial, the shank adapter must be engineered to withstand the most extreme stress. Its function is to transmit impact energy from the rock-drill piston, as well as rotation torque, into the drill string without energy losses. It must withstand and transmit up to 6300 blows per minute from the piston continually, with great endurance and dependability.
TOP HAMMER INTEGRAL DRILL STEEL (IDS)
Integral drill steels are crucial for peak productivity in all applications. Sandvik drill steel has a high fatigue strength and toughness, and offers the highest wear resistance that ensures an efficient and economic drilling operation. When you partner with Sandvik, you can expect consistantly high quality and maximum operational dependability when it comes to small hole drilling applications.
ALPHA 330 TOP HAMMER DRILLING TOOLS
Today’s rock drills generate almost unlimited impact power. We need to control that power and, most importantly, ensure that it is transmitted into the rock as efficiently, accurately and economically possible. That is the job of the rock drilling tools, which is why we continue to develop the Alpha 330 tool system – to bring the best solution for performance and productivity. The drill string rod/bit connection features an entirely new thread design and the rod itself is, with a T38 thread at the shank end. The rods new short thread design results in a rigid, integrated power pack drill string. A superior resistance to bending stresses along with improved bit guidance results in a perfect energy transfer. The sturdy thread is well guided inside the bit skirt, offering high precision in collaring – even in complex rock formations and against uneven surfaces.
SANDVIK GUIDE ADAPTER
Reduced hole deviation is key to achieving greater productivity, longer tool service life, improved safety and ultimately lower operational costs.A guide adapter can also decrease the number of holes, the amount of secondary blasting and the consumption of explosives. Tests have proven that using our Guide Adapter in challenging conditions, such as bad rock, deep overburden, fractured and variable rock formations as well as for soft rock can improve your hole quality and hole straightness with up to 50%.
