Cutting the first 8 chars of a 2nd column

I am having a stupid moment :-)

I have a tab-delimited file with 2 columns. I want to keep the first column as it is, but I only want the first 8 characters of the 2nd column.

Code:
Example of input file data:
---------------------------------
CATERPILLARS	CW001651K.dwg
CATERPILLARS	CW001683W.dwg
DUNG BEETLES	DU001751.dwg
DUNG BEETLES	DU001759.dwg
DUNG BEETLES	DU001765_1_2_7455.bak
DUNG FLIES LG	DF001765.dwg
DUNG FLIES XL	DX000211Q.dwg
SLUGS GREEN	SG000282-1110.dwg

Desired Output:
---------------------------------
CATERPILLARS	CW001651
CATERPILLARS	CW001683
DUNG BEETLES	DU001751
DUNG BEETLES	DU001759
DUNG BEETLES	DU001765
DUNG FLIES LG	DF001765
DUNG FLIES XL	DX000211
SLUGS GREEN	SG000282

Thanks very much in advance.

COLRM(1)						    BSD General Commands Manual 						  COLRM(1)

NAME
colrm -- remove columns from a file SYNOPSIS
colrm [start [stop]] DESCRIPTION
The colrm utility removes selected columns from the lines of a file. A column is defined as a single character in a line. Input is read from the standard input. Output is written to the standard output. If only the start column is specified, columns numbered less than the start column will be written. If both start and stop columns are spec- ified, columns numbered less than the start column or greater than the stop column will be written. Column numbering starts with one, not zero. Tab characters increment the column count to the next multiple of eight. Backspace characters decrement the column count by one. ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7). EXIT STATUS
The colrm utility exits 0 on success, and >0 if an error occurs. SEE ALSO
awk(1), column(1), cut(1), paste(1) HISTORY
The colrm command appeared in 3.0BSD. BSD
