Steelex Plus D4521 - 3/8" HSS Brad Point BitD4521 3 8" HSS Brad Point Bit Just the replacement pointed drill bit you need. The D4521 3 8" HSS Brad Point Bit was designed with a center pin or Brad Point to keep the bit from wandering. Brad point bits drill straight, clean holes in wood far better than standard twist bits. They can also be used to drill through plastics, but are not for drilling through metal. The D4521 is made from HSS or high speed steel and has been heat treated for hardness

Great little bang for buck and DIY savings from the Dealership Service DEPT
Easy to install and very simple to place into the correct compartments in the glove box and engine bay. Took maybe 15 minutes or less. Quality is great and the air in the cabin is so fresh now! The quality of the air filters is OEM+ which is great when trying to save some money and add value to the product. Fits perfectly in my 2020 Honda civic Sedan. Includes everything needed to replace both filters. Includes both cabin and engine air filter

Fits 2017 Honda Civic
This fit perfect for my 2017 Honda Civic. It looks and feels super similar to the ones I removed so they seem of equal quality. As for value? Can't beat it!
