There is a cross drilled hole in the round portion of the handle, about 1-1/2 back from the 90 degree head. The hole goes thru the black handle and the inside shaft (you will have to turn the shaft or drill till the holes line up). Use an 1/8 drill shank, or a scribe, or anything about 1/8 diameter to go into the hole.

Though both [NiCl4]2− and [Ni(CO)4] are tetrahedral, their magnetic characters are different. This is due to a difference in the nature of ligands. Cl- is a weak field ligand and it does not cause the pairing of unpaired 3d electrons. Hence, [NiCl4]2− is paramagnetic.

Nickel is a silvery-white metal that is used mainly to make stainless steel and other alloys stronger and better able to withstand extreme temperatures and corrosive environments.

Frequently Asked Questions – FAQsQ1 Is [NiCl4]2− paramagnetic? Though both [NiCl4]2− and [Ni(CO)4] are tetrahedral, their magnetic characters are different. This is due to a difference in the nature of ligands. Cl- is a weak field ligand and it does not cause the pairing of unpaired 3d electrons. Hence, [NiCl4]2− is paramagnetic. Q2 Why is [Ni(CN)4]2- square planar? In presence of strong field CN– ions, all the electrons are paired up. The empty 4d, 3s and two 4p orbitals undergo dsp2 hybridization to make bonds with CN– ligands in square planar geometry. Thus [Ni(CN)4]2- is square planar. Q3 What is the IUPAC name of [NiCl4]2− negative? Tetrachloronickelate (II) ion is the metal complex with the formula [NiCl4]2−. Q4 What is nickel used for? Nickel is a silvery-white metal that is used mainly to make stainless steel and other alloys stronger and better able to withstand extreme temperatures and corrosive environments.

Works well, just the tool was a bit dinged up. Tools in that price range should look immaculate on arrival. The bits were untouched but the body had some marks.

Very well-made tool. I used a cordless drill to drive it, not my air drill, but it got the difficult job done correctly the first time.

In presence of strong field CN– ions, all the electrons are paired up. The empty 4d, 3s and two 4p orbitals undergo dsp2 hybridization to make bonds with CN– ligands in square planar geometry. Thus [Ni(CN)4]2- is square planar.

Ni2+ undergoes sp3 hybridization to make bonds with Cl– ligands in a tetrahedral geometry. As there are unpaired electrons in the d-orbitals, [NiCl4]2− is paramagnetic and is referred to as a high spin outer orbital complex. Therefore [NiCl4]2− are tetrahedral.

This kit has a 90 degree adapter that can be fitted to a normal drill that Im sure works fine. I bought the kit for the assortment of bits and the case. I am using this with an ATS 90 Degree Angle Drill. The bits fit perfectly. They cut though aluminum fast and clean. Great product.

The stall torque would be the torque on the actual / specific air or electric or battery powered drill motor that is chucked to the 90 degree drill attachment. Since there are so many variables and types of drill motors being used by mechanics, each mechanic would need to determine the actual manufacturers stall torque on his or her personal drill motor. Also on air drills, the amount of air pressure used may have a variance on the torque at the drill motor chuck.

Overall height of the 90 degree head with the chuck installed is 2" (inches). The head is 1.100" and the chuck is .900" height. Then whatever drill length has to be added. The chuck diameter is .800" round, and the angle head diameter is .700" round.
