Carbide Inserts

Black Diamond Drilling has developed a range of high performance and high durability Carbide Inserts for all industrial needs. By utilising the latest technology with the most advanced manufacturing equipment from Switzerland and Germany. BDDrill can supply the highest quality and most precise range of Carbide Inserts for any application.

Introduction of Turning Material

7215 - One matrix with high strength, toughness and high wear-resisting, excellent combination of coating process with MT—TiCN, thick AL203, TIN and removed interior stress in layer after the advanced coating further. It is suitable for ordinary steel finish machining.

7125 - The good safety edge of blade with high strength and flexible matrix combine with coating process of MT—TiCN ' s super—thick AL203 and removed interior stress in layer after the advanced coating further. It is suitable for ordinary steel rough machining, semi-finish machining and some of workpiece has no high requirement on its roughness.

4025 - With high wear resistance made by sintered process with a certain pressure and high strength matrix a great combination with MT—TiCN and super—thick AL203, and with advanced coating following process to get a smoothly coating surface. It is suitable for rough machining in cast iron, semi—finish machining and finish machining.

1030 - Fine grain, perfect non—deformability and super high strength and wear resistance matrix that made by pressure sintered process, with nanometre PVD coating process and advanced following coating process to get a smoothly coating surface. It is suitable for ordinary steel' s finish machining, quenched steel, Chromium—plated steel and stainless steel' s semi and finish machining.

1120 - Ultrafine grain, perfect non—deformability and super high strength and wear resistance matrix that made by pressure sintered process, with nanometre Si included PVD coating process and advanced following coating process to get a smoothly coating surface. It is suitable for ordinary steel' s finish machining, quenched steel, cast—iron grooving and cut off machining.

Milling Drilling Material Information

1030 - NC—TiALN coating combination with a fine grain and high strength matrix suitable for all kinds of workpiece in rough, semi—finish milling, grooving, cutting off and drilling of normal diameter of hole.

1130 - Si included NC—TIALN coating combined with fine grain and good toughness cemented carbide matrix suitable for stainless steel, cast—iron' s rough milling and semi—finish milling getting a wonderful combination in safety and wear—resistance.

5035 - CVD coating with added elements of wear—resistance and high temperature resistance to provide an effective protection for cutting edge with its high hardness of coating layer and excellent high temperature resistance. Special coating technology to ensure the connection between coating and matrix getting more stronger suitable for precision milling in high temperature alloy steel, Titanium alloy steel.

5135 - Containing element Si the coating of NC—TIALN combine with cemented carbide matrix with its good impact toughness, suitable for steel workpiece, stainless steel, grooving, cutting in depth, fasting feeding and bigger size of hole drilling.

Testing Report of Blade Performance Comparison

Purpose of Testing: Comparison of overall performance of the blade and optimisation of the blade material.

Summary of Blades tested:

7115 Black Diamond Drilling

Blade from Large Private Company

Blade from Small Private Company

Blade from Famous Brand

Blade from another Famous Brand

Cutting Tools: DWLNL3225P08

Cutting Material: #45 Steel

Cutting Parameters:

1. V=350m/min f=0.2mm/z ap=1mm

2. V=320m/min f=0.3mm/z ap=2mm

Cooling Conditions: None

Results of Testing:

Under identical working conditions, no blade had abnormal failure. The cutting process was stable, and the result of the life span test was deemed reliable.

The results show that Black Diamond Drilling’s 7115 blade has the best overall performance, the large private company also had a satisfactory result. The 2 famous brands have unsatisfactory results showing premature wear. The small private company had the worst result as seen in the data below.
