Different Types Of 38mm Tapered Bit For Rock Drilling

Tapered bit?also refer to?tapered button?drill bit?or small hole taper drill bit, which work with tapered drill bit and rock drill machine for rock drilling. The drill bit is has cemented carbide embedded in the drill body and work with tapered drill rod. This drill bit are mostly work in mining, tunneling, anchoring engineering, quarrying and other industries. 38mm taper drill bit refer to the cutting hole diameter of the bit is 38mm. Bellow are more details about the 38mm tapered drill bit:

Introduction of 38mm tapered bit

Specifications

1. Taper angle: 4° 6°7° 11° 12°,commonly use 7° 11° 12°.

2. Button number: 4,5,6,7,8 buttons

3. Flushing hole: 1-4

4. Skirt length: 50mm,55mm and 60mm.

5. Types: Chisel, Cross and Button type

Different Types

1. Taper Chisel Bit

A tapered chisel bit has a?straight-shaped carbide cutter head on the top of the drill head. It is suitable for light rock drills to drill holes and is suitable for rock formations with low hardness. It is widely used in mines, as well as railway, highway and water conservancy construction.

Features:

A. Using?high-quality steel and alloy, with high toughness and wear resistance, high production efficiency.

B. Simple manufacturing technology, easy to use, low price, strong adaptability to rock mass performance.

C. It can smooth out sudden changes in drilling conditions during drilling work on rock, coal, concrete, etc. It makes the drilling work stable, and the drilling efficiency will not decrease even when?there are?large chip.

2. Tapered Cross Bit

The cross drill bit?has?a cross shape?head, with four pieces of alloy. The cross drill bit is mainly work to drill blastholes, such as rock holes, coal holes, concrete holes, etc.

Feature:

A. Using high-quality steel and alloy, it has high toughness and high wear resistance, high production efficiency and low cost.

B. The cross drill bit will not break during the drilling process. It is conducive to saving labor and speeding up the project.

C. It has strong adaptability to rock drilling conditions, especially in strong and extremely strong highly abrasive fractured rocks.

3. Tapered Button Bit

The tapered button bit is the?most popular tapered drill bit?for modern rock drilling technology.?The strongest part of the button bit is the carbide buttons on the head, which use wear-resistant alloy.

Features:

A. Long service life, accurate positioning, coarse rock cuttings, low dust, long-lasting.

B. Compared with traditional?chisel?drill bits, the drilling speed is fast.?the button?drill bit has a long passivation cycle, and its service?life is about 5-6 times?longer.?
