Tungaloy has expanded its DrillMeister exchangeable-head drill system by adding 24 more DMH drill heads that are designed to resist fracture damage. This addition is for hole diameters ranging from 6.0 to 9.9 mm (from .236″ to .390″) and from 20.0 to 25.9 mm (from .787″ to 1.020″).
DrillMeister features superior cutting performance of solid carbide drills and the ease-of-use of the exchangeable head drill system. A single drill body can hold five different styles of drill heads, which are available in general purpose DMP style, DMC for high precision holes, DMF with flat edges ideal for counterboring, DMN for non-ferrous applications, and DMH with enhanced drill corner geometry for drilling thin plates.
The DMH drill head geometry is designed to protect drill corners and provide effective chip evacuation, making the drill head suited for applications that involve drilling holes through thin plates. The increased cutting edge strength resists thin-plate snapback and wear from exit burrs, preventing drill edges from fracture damage during machining for minimum machine downtime. The strong cutting edge also makes the DMH drill head suitable for drilling extremely hard metals.
AH9130 grade provides DMH drill heads with a good balance of wear and fracture resistance, ensuring exceptional tool life performance and wear predictability, particularly in carbon steel and alloy steel.
Enlarging one end of a drilled hole. The enlarged hole, which is concentric with the original hole, is flat on the bottom. Counterboring is used primarily to set bolt heads and nuts below the workpiece surface.
AddInternalCut inserts are available in two sizes: TCIG10 insert is for internal grooving of minimum bore diameter of 10.5 millimeters (.413 inches) and up. TCIG12 allows a maximum groove depth (CDX) of 3.0 millimeters (.118 inches).
Together with successful AH7025 grade for first choice, AH6235 and AH8005 grades will enhance TungCut performances in parting and grooving operations with interruptions, as well as grooving and turning operations with aggressive conditions.
SolidMeister barrel endmills are efficient tools for complex 3D surfacing operations used in mold making, orthopedic implant work, and the machining of gas turbine blades and other freeform surfaces in the aerospace and energy industries. The endmills incorporate a cutting edge that is actually the…
SDM chipbreaker features unique T-land with variable widths and optimized rake angle that provide the insert with resistance against notch wear. Difficult metals like HRSAs are prone to cause notch wear on the insert cutting edge that can severely deteriorate insert tool life. A combination of SDM…
The series is now introducing TCS18 and TCL18 inserts designed for left-hand cuts, expanding the product lines that, up to now, has offered right-hand inserts only. Grooving and parting tools commonly used in most of the operations performed in conventional CNC lathes and Swiss machines are right-…
BallFinishNose is an effective tool in finishing and semi-finishing, particularly on geometric surfaces and complex 3D contours common to die-mold or aerospace applications. The insert features a unique asymmetric shape. This design allows users to use the same side of the insert always facing the…
The DMH drill head features a fracture resistant design that is suitable for applications that involve drilling holes through thin-walled sections of workpieces. In normal circumstances, thin walls tend to spring back on the drill after the drill pierces through and exits the hole. In the process,…
DrillMeister drill sleeves are available in 16, 25, and 32 millimeters in diameters for metric sizes and 3/4 inches and one inch for imperial sizes that fit the drill holders of the same sizes equipped in Swiss lathes. All drill sleeves have a threaded connecting port on the sleeve end for easy…
Tungaloy has expanded its economical, double-sided negative insert line with the -28 chipbreaker. Featuring a pressed-in chipbreaker geometry with a large inclination angle on the sharp cutting edge, the -28 generates free cutting action with superior chip control. In addition, a negative insert…
FixRMill uses round inserts for machining dies and molds, especially complex male-female main parts such as cavities and projections. The round inserts feature anti-rotation notches on the insert clearance side and matching locations on the pocket seats. These notches not only prevent the insert…
