Drill Extensions

Star Cutter Express

Express In-Stock Gundrill Programs, Custom Designs Also Included

There are two stocked and standard product offerings where gundrills are delivered within 24 hours of the order. The SFGD Express program is for Single Flute Gundrills in diameters from 0.1250” - 0.7500” (3.175mm - 19.050mm) and lengths up to 48” (1219mm). The SCGD Express program is for Single Flute Solid Carbide Gundrills with standard ½” steel shanks in diameters from 0.0355”- 0.1969” (0.902mm - 5.000mm) in lengths from 4”- 12” (102mm - 305mm), depending on the tool diameter.

D3120 Indexable Insert Drill

insert Drill Features Superior Hardness, Coolant Flow, Optimum Reliability

Available in diameter sizes ranging from 0.562-1.375 in. and 16-42 mm with 2, 3, 4 x Dc, the new drill delivers maximum process reliability with simple and efficient chip removal, two coolant channels and polished flutes. Superior protection against friction is provided by the D3120 hardened and polished surfaces. This combination of surface hardness and improved coolant flow results in reduced wear on the drill surface.

New DeepTri-Drill drilling depth capabilities

DeepTri-Drill Offers up to 45xD Drilling Depths on Standard CNC Machines

DeepTri-Drill is designed to provide productivity and application security for drilling deep holes on standard machining centers and CNC boring machines, while ensuring easy tool management by eliminating the need for regrinding. The insert features chip splitters that allows effective chip evacuations enabling extremely high feed rates during deep hole drilling in various materials.

KenTIP FS FEG Insert

FEG Insert for Flat Bottom Hole Applications

Drilling flat-bottom holes is a challenge. So is drilling on inclined or curved surfaces, drilling into cross holes, drilling stacked plates, and drilling into cross holes, stacked plates and castings and other rough surfaces. Not anymore. Leveraging the success of its KenTIP FS modular drill, Kennametal has developed a unique insert geometry (FEG) that streamlines many of these types of applications and simplifies the drilling of counterbores and pilot holes as well.

FH3125 Grade Guide Pad

FH3125 is a new grade specifically developed to enhance the guide pad’s wear resistance in machining various materials. The dedicated carbide substrate of the grade is designed to reduce guide pad breakage, providing long and predictable tool life in deep hole processes. The corners of both ends of the guide pad are designed to allow smooth entry into the guide bushing or pilot hole to control vibration impact and further decrease the risk of rupture.

FINE BEAM Inserts

The latest additions include inserts with 0.8 mm (.032″) nose radius in versatile AH725 grade. 0.8 mm nose radius will provide the cutting edge with strength, preventing edge fracture for predictable tool life. In addition, AH725 enhances the insert’s wear resistance during machining of various materials, ensuring high precision and boosts productivity.

Solid Carbide Gundrills

Small diameter gundrills have resulted in cost savings. This was driven from tool life and throughput improvements, including several case studies that were done that resulted in doubling production capability

DrillMeister Chamfering Holders

DrillMeister offers the TIDCF chamfering holder that can be attached to the TID drill shank allowing chamfering and drilling in a single pass for reduced machining times. The chamfering inserts are available for 30°, 45°, and 60° chamfers. The new TIDCF holder line can accommodate smaller drills in diameters from 7.5 mm to 9.9 mm (.295" - .390") for improved machining processes.

Expansion of Grade AH9130 to DMP Drill Head Line

DMP drill head are expanded in diameters from 10.3 mm through 19.8 mm

This AH9130 grade expansion encompasses the DMP line of general-purpose drilling, succeeding the popular DMC drill head for precision drilling. Developed for drilling applications, AH9130 is a nano-multilayer PVD coating consisting of three distinctive layers.
