How to repair M10x1.25 thread?
For an M10x1.25 thread repair with a Keensert, a 12.5mm drill would be used for the M14x1.5 tap. The M14x1.5 tap would have a major diameter up to 14.4mm (an M10 repair with an S.T.I. tap would only have a 11.787mm major diameter). That’s a much bigger hole which can be beneficial in some application where severe corrosion is prevalent in the original threads. The Keensert would then be threaded into the drilled, tapped and cleaned hole with the Keensert installation tool. Thread locking compounds can be used due to its solid body design. Once set in position, the installation tool is then used to drive in the four key stakes into position. This provides the ultimate mechanical locking of the insert in place. Hence, this design sports exceptional resistance to vibration. Now the downside. The massive outside diameter of the insert makes it unviable in applications where the material around the original threaded hole is limited, such as any “thin-wall” castings. Second, the cost for a standard-steel Keensert is about 4.5 times that of a HeliCoil and more than double the cost of a TIME-SERT. If you want a stainless-steel Keensert, the cost goes through the roof being about 25 times the cost of a HeliCoil.

What Causes a Stripped Screw Hole?
A stripped screw hole results from two factors: the failure to use enough pressure when tightening and metal fatigue. Over time, screws are repeatedly tightened into the same spot with insufficient force or not removed fully, causing them to bind up in place. Over time these repeated cycles will cause slight permanent damage to the surface, leading to stripping.
How to apply safety tape to drill bit?
When applying safety tape, start by cutting off an appropriate length. Place it around the head of your drill bit with plenty overlapping onto the screwdriver or stripping tool you are using.

Cut any excess safety tape away as needed before continuing work.
