●HSS G core hole drill for metric normal thread in different quantities
●The drill bits are suitable for drilling steels up to a tensile strength of 800 Nmm². Not to be used for stainless steel or high-alloy steels
●The core hole drill bits with 2.6/3.4/6.9/8.6 mm are 0.1 mm larger in the core hole. (The taps are protected and do not break so quickly, especially with thick and tough material)
●The cooling of the drill bits is very important, otherwise the drill will glow and will no longer be used. You can buy the coolant from me in my shop. The cooling is very important as otherwise the drill will glow and will no longer be used. You can buy the coolant from me in my shop.

Description

Core hole drill for metric thread individually 1; 5 or 10 pieces or a practical set. For drilling work with high stress and greater concentricity in metal, e.g. steel, sintered iron, etc. Drill material: HSS 42CrMo4 material processing up to a tensile strength: <800 N/mm². The offered 14.0 mm drill is a HSS G Profi Plus drill for the highest demands up to a tensile strength of 900 N/m². Drill material: AISI M2 DIN 1.3343 JIS SKH51 steel. Other sizes of this quality can be found in my eBay shop. The offered drill bits 2.6 mm M3; 3.4 mm M4; 4.3 mm M5; 5.1 mm M6; 6.9 mm M8; and 8.6 mm M10 are very suitable for fixings that do not require the full tensile force of the thread. Such as attaching sockets, switches or small parts that are very light. This has the huge advantage that the taps cut 3-4 times longer. Set contents: 11 core hole drill bits 2.5 mm for M3, 2 pieces 3.3 mm for M4, 2 pieces 4.2 mm for M5, 2 pieces 5.0 mm for M6, 2 pieces 6.8 mm for M8, 1 piece 8.5 mm for M10, 1 piece 10.2 mm for M12, 1 piece
