Frequently Asked Questions (FAQ)
Q1: What is a 32mm tapered button drill bit?
A1: It is a small rock drill bit featuring a 32mm head diameter and a tapered connection (typically 11 degrees) designed with hot-pressed carbide buttons for drilling holes in medium to hard rock formations.
Q2: What connection degrees are available for these small rock drill bits?
A2: The drill bits are manufactured with taper connection configurations of 7 degrees, 11 degrees, and 12 degrees to match various rock drill rod specifications.
Q3: How does the forging and heat treatment process benefit the drill bit?
A3: Forging and heat treatment enhance the structural integrity and toughness of the steel skirt, preventing breakage under impact and extending overall drilling longevity.
Q4: What sizes of skirt bodies are available for the button bit?
A4: The standard skirt body lengths available are 50mm, 55mm, and 65mm, depending on the specific drilling requirements.
Q5: Why are tungsten carbide buttons used on the bit skirt?
A5: Carbide buttons are extremely hard and wear-resistant. Hot pressing them onto the skirt provides superior rock crushing capability and prevents premature wear in abrasive rock conditions.
Q6: Can I choose the color of the drill bits?
A6: Yes, the drill bits can be finished in various colors such as yellow, black, red, green, and others, according to customer specifications.
