Maxdrill Rock Tools Co., LTD supplies 12 degree taper button bits in 32 mm and 33 mm diameters, designed for percussive drilling in hard rock formations. The bits use a tapered shank that seats into a matching drill steel socket, transferring impact energy efficiently from the rock drill to the cutting face. Tungsten carbide buttons are brazed into the bit head to provide wear resistance in abrasive ground conditions.
Taper button bits in this class typically feature a button configuration of 4 to 6 inserts arranged across the gauge and centre positions, with button diameters ranging from 7 mm to 9 mm depending on the bit size. The 12 degree taper angle is a common standard in light-to-medium rock drilling, compatible with standard tapered drill rods from most manufacturers. Typical hardness of the carbide tips falls between 87 and 89 HRA, suitable for drilling compressive strengths up to approximately 200 MPa.
These bits serve mining, tunnelling, quarrying, and construction foundation drilling operations. Maxdrill Rock Tools offers flexible MOQ and accepts payment via L/C and T/T, with FOB and CIF shipping terms available. Buyers should confirm exact pricing, current stock of each diameter, and lead times directly with the supplier, as these details are not published on the listing.

Before ordering taper button bits from Maxdrill Rock Tools, confirm the exact taper angle compatibility with your existing drill steel. While 12 degree is a widely used standard, slight variations exist between manufacturers. Request a dimensional drawing or sample to verify the taper fit, shank length, and overall bit geometry against your drill rods and rock drill model.
Discuss logistics and trade terms in detail. Maxdrill is based in China and offers FOB and CIF shipping, but the specific port of loading is not stated. Ask which Chinese port they ship from, typical container loading quantities for 32 mm and 33 mm bits, and estimated transit times to your destination. Clarify whether CIF pricing includes marine insurance and at what coverage level. For T/T payments, negotiate a deposit-to-balance split that protects both parties.
On delivery, inspect a sample from the batch for button brazing quality, taper surface finish, and dimensional accuracy. Check that the carbide buttons are firmly seated with no visible gaps at the braze joint, and measure the taper angle with a gauge if possible. Bits that show poor brazing or inconsistent taper dimensions will not seat properly in the drill rod and can cause premature failure or jamming in the hole. Keep records of bit life (metres drilled per bit) in your ground conditions to benchmark future orders.
