Trim head screws are great for installing trim moldings in softwoods, but generally require pre-drilling in hardwoods to avoid splitting, or worse yet, stripping of the recess. Standard countersinks either have too large a countersink or too small a pilot bit. The result is an oversized head hole that requires excessive filling, or a pilot hole that isn’t big enough to clear the screw threads. Our new trim head countersink drills a 1/8" clearance hole and has a 1/4" diameter countersink that fits most trim head screws perfectly. You will need to eye-ball the depth. On countersinks this small, the use of a stop collar prevents wood chips from clearing, leading to heat build up, which can prematurely dull the edge on the countersink. Made in USA.

Comments about 1/8'' Dia. Std. Point x 1/4'' Trim Head Countersink:
Used in conjunction with trim screws to attach a row of bookcases together. The size of the drill bit and countersink are ideal for use with smaller heads on trim screws. Although there is provision for adjusting the length of the drill bit there needs to be a stop collar to limit the depth of the countersink.
Bottom Line Yes, I would recommend this to a friend

Use with trim work or anywhere you want a secure screw connection with low or no profile.

For woodworkers who do fine finishing and cabinetry or custom mantals this is an important addition to your arsenal of accesories. Using trim screws give much greater holding power over nails and the slew of advantages that has in many applications. Both at shows and thru local companies they are rarely inventoried. Thank you McFeely!

Drills very well. I used on IPE Tongue & Groove lip to predrill for stainless steel trim head screws. On 600 sq ft of 3" decking, I went through 8-10 bits.

Takes a bit of getting used to in order to hit the "sweet spot" (not too deep or too shallow), but once you get the hang of it, it will provide clean countersinks at the proper depth.The area where the bit and countersink come together frequently clogged with chips while drilling composite decking.The 1/8" bit is actually a bit too large for many trim screws.
