Bits Profile

Description:A moderately abrasive type of bit, Ideal in medium to hard ground conditions where fast
penetration is required and straightness is less critical. Button bits are categorized by a variety of criteria:
bit diameter, skirt length, skirt diameter, wall thickness, gauge clearance angle, face design and button
insert types.

Skirt Design

Our button bit skirt designs can be split into two categories: Retrac and Straightrac

Retrac

The Retrac skirt features an extended body, with cutting edges or ribs designed into the skirt. This design ensures easy removal and completion of the bit in adverse ground conditions.

Straightrac



The Straightrac skirt features an angled flute design with an extended skirt body that maintains 360° contact in the hole. The Straightrac design has been field tested and proven to provide straight holes in even the most adverse ground conditions.

Face Design

Depending upon ground conditions, size of the bit, abrasive qualities of formation, rate of desired penetration and desired straightness of the hole, the following bit faces can be selected to match the requirements

BR - Button Recessed

Ideal for straight hole applications in broken ground, button recessed bits are characterized by a unique "drop center" face design.

BF - Button Flat

Defined by their flat face design, these general purpose bits are designed to be effective in medium to hard ground conditions.

BF - Button Chisel

With a distinct chisel shape, this fast-penetrating style of bit is perfect for abrasive conditions, and is often utilized in trunneling applications

BD - Button Dome

Featuring a clearly defined raised profile, this style of bit is used primarily in reaming applications in soft ground.

 

Insert Type
Matching the insert to the job requirements is essential in achieving the desired results.  Each of the following buttons is ideal for different ground conditions, abrasion levels, PSIs and penetration levels.  In general, the larger the number of gauge buttons the better overall performance, especially in hard rock.
 

Number of Buttons

33 mm - 45 mm - 3 - 6 buttons

45 mm - 51 mm - 4 - 6 buttons

51+ mm - 6 - 10 buttons
 

 

Hard Rock - Larger Ø

Medium Rock - Smaller Ø

Soft Rock - Smaller Ø

DOMED (SPHERICAL)

This type of button is the most common shape utilized in Threaded Button Bits and DTH bits.
This type of shape is the strongest and most resistant to breakage. The domed shape
provides excellent penetration in medium rock, hard rock, and hard rock broken
formations under most types of drilling conditions.
BALLISTIC
Normally this type of button is only used in soft consolidated drilling formations.
This type of button is very aggressive and tends to drill very quickly. However, due
to the ballistic shape it is prone to breakage if used in the wrong formations. Care
should be used when drilling with this type button. Ballistic buttons do yield high
penetration rates and efficient rock breakage.
